Penstemon hirsutus – EASTERN PENSTEMON, HAIRY PENSTEMON

Posted in Full Sun, Mid Height, Perennial, Plant Portraits, Purple, Summer, White, Xeriscape, tagged , , , , , on November 17, 2014|

Perennial. Zone 3. Plantaginaceae, formerly Scrophulariaceae. Syn. Penstemon pubescens. A.k.a. HAIRY BEARD-TONGUE. North America. In Canada, from Ontario eastward. The entire plant – leaves, stems, buds, flowers – is entirely covered by tiny, silky hairs, hence the Latin and common names.

Penstemon hirsutus is an attractive North American wildflower which is widely grown in gardens. There are numerous forms, including a dwarf type, Penstemon hirsutus ‘pygmaeus’, which is very popular in alpine gardens. Colours may range from pure white through pale lavender to rosy tones – but the most common is the blushed lavender pictured above.

This Penstemon is a quietly  elegant, rather understated plant. The foliage clumps are attractive, being composed of smooth, satin-textured, dark green, lanceolate leaves. Its roots are rhizomatous, and the plant slowly expands from its center. Penstemon hirsutus is completely non-invasive. Mature plants may be carefully divided and replanted in early spring to prolong the plant’s life, as they can get quite woody and die off  in the centers.

Slender stems arise in early summer, 18 to 30 inches tall. These are lined with loosely arranged whorls of small, pale-purple-flushed-with-darker-highlights, tubular flowers in late June through July. The buds and flowers have a silken sheen which rewards a closer look.

A rather beautiful plant, though not at all what one could call “showy”. I am fond of it, for its ease of growth and self-sufficiency – no need of staking or pruning or any sort of fussing –  and its profuse blooms, always alive with bees. All of the Penstemons are great hummingbird favourites, and this species is no exception.

Penstemon hirsutus is happy in any average garden soil. It is drought tolerant and can be used in xeriscape plantings, but will get larger and bloom more with at least a bit of supplemental moisture in the hottest months of summer. Full sun is best, though it can tolerate part-day light shade. A pleasant front-of-border plant.

Penstemon digitalis – ‘MYSTICA’ PENSTEMON

Posted in Full Sun, Mid Height, Perennial, Purple, Summer, White, Xeriscape, tagged , , , , , on November 16, 2014|

Perennial. Zone 4. Scrophulariaceae. Mid-Eastern North America, including Manitoba, Ontario and Quebec. A.k.a. FOXGLOVE PENSTEMON.

Some years ago Penstemon digitalis ‘Husker’s Red’ was absolutely everywhere, and being touted as something of a wonder plant – “Long blooming!” “Beautiful foliage!” “Drought tolerant!”  It was the Perennial Plant Association’s “Perennial of the Year” in 1996, which is generally a recommendation of good garden merit, but in this case I do believe the hype was greater than the plant proved to be. I grew it for a few seasons and thought it nice enough in a minor-key way, but when it succumbed to a not-particularly-hard winter, I shrugged and moved on.

‘Mystica’ is the offspring of ‘Husker’s Red’, and has proven to be a generally better plant than its parent. Released in 2008, ‘Mystica’ is not receiving nearly as much promotion as its ancestor, but the word in the gardening world is uniformly positive. I’ve been growing it for four or five seasons now, and I have found it quietly attractive and reliably hardy.

Penstemon digitalis is a showy North American wildflower, widely adapted to various soils and happy in full sun to light shade. It is drought resistant to the point of being included on xeriscape lists, though the nicest specimens are those which receive at least a bit of attention in the way of decent soil and some summer moisture. Both ‘Husker’s Red’ and ‘Mystica’ are selections of the species, developed by choosing the seedlings with desirable traits (dark foliage, showy flowers, long bloom time, hardiness) through successive generations.

‘Mystica’ makes a tidy clump of purple-flushed, silky-smooth foliage. 18 to 24 inch tall bloom stems emerge in early summer, and produce pretty, white-blushed-with-purple rather foxglove-like blooms for 3 to 4 weeks. Once the flowers drop, the glossy purple seed pods provide garden interest. The foliage stays attractive right until first snowfall, responding to cooler autumn temperatures with a reddening of its dusky leaves.

As with all of the Penstemons, hummingbirds love ‘Mystica’, as do numerous types of bees and other insects. It is nice towards the border front, and is tidy enough for the rock garden. In general, a good plant, attractive for three seasons and adaptable in a wide range of conditions.

‘Mystica’ is propagated by seed, so plants are a bit variable as to ultimate height and coloration of foliage. Occasionally a mostly green plant shows up in a batch, but when I kept a few of these instead of rogueing them out, I found them to be perfectly acceptable, blooming away nicely with their showier-foliaged siblings, and adding some contrast to the small colony in my garden.

Echinops ritro – BLUE GLOBE THISTLE

Posted in Blue, Full Sun, Late, Mid Height, Perennial, Plant Portraits, Summer, Tall, Xeriscape, tagged , on November 16, 2014|

Perennial. Zone 2. Asteraceae, formerly Compositae. East-Central Europe, Asia.  The genus name is from the Greek echinos = “hedgehog-like” (in some references “sea-urchin-like”) – in reference to the spiky structure of the bloom; ritro = “of gardens”.

This is often the first Globe Thistle every gardener starts out with – my original plant is alive and well and giving great pleasure more than twenty years after I received a hefty division of it, overflowing its disintegrating cardboard box, from a fellow-gardener friend. I’d admired her gorgeous dried flower bouquets containing the perfectly round, frosted blue Globe Thistles at an early autumn farmers’ market, and she remembered my interest the following spring.

Though the common name “thistle” might cause the neophyte Echinops grower some initial concern, the prickles on this plant are soft and benign. The lush, dark green, raggedly-cut foliage is tipped with flexible points, but they do not detach, and the plant can be handled easily with bare hands.

Echinops ritro is a clump former, with a height of 2 to 4 feet or so, depending on soil fertility and moisture, and a spread of about half its height.

Sturdy stems covered by fine white hairs produce perfectly globular buds in mid-summer, and these enlarge and expand and take on an increasingly intense blue tint, until the tiny electric-blue flowers pop open one by one and immediately attract bees, butterflies, and a host of other nectar and pollen seeking visitors. Bloom time of the large golf ball-sized and -shaped flower clusters is extended, easily 6 to 8 weeks or more, and the aging flower heads stay attractive well into fall, when they will be visited by chickadees and other small birds which relish the seeds.

Echinops ritro is hardy and drought tolerant, but produces the best show in good garden soil with summer moisture. It spreads modestly at the roots, expanding its clump year by year, and it will also self sow in a mild way. Plants are tap rooted, but mature clumps may be divided with care in early spring.

Full sun to light shade is acceptable to this plant. It combines beautifully with the other blue garden thistle, Eryngium planum (Blue Sea Holly), as well as fall-blooming sedums such as Hylotephium x ‘Autumn Joy’, any of the Rudbeckias, and all sorts of ornamental grasses.

Malva moschata ‘alba’ and ‘rosea’ – MUSKMALLOW

Posted in Full Sun, Mid Height, Perennial, Pink, Plant Portraits, Summer, White, tagged , , on November 15, 2014|

Malva moschata 'rosea' 'Rose Perfection' Musk Mallow - Hill Farm, July 2013. Image: HFN

Malva moschata ‘rosea’ – ‘Rose Perfection’ Musk Mallow – Hill Farm, July 2013. Image: HFN

Perennial. Zone 2. Malvaceae. Europe, North Africa.

When I was recently listing all of the “old faithful” nursery plants we seem to offer year after year after year, the Musk Mallows, pink and white, were at the very top. And I doubt this situation will change, for Malva moschata is one of the easiest perennials there is, though it does have its faults, the main one perhaps being its relatively short life span, which is balanced by its willingness to self sow, which is in turn balanced by the ease with which the seedlings can be recognized and removed from unwanted areas.

Musk Mallow is so named for the scent of the foliage when bruised, moschata meaning “musk-like”, though I must say that I have never particularly noticed much more than a general “green” scent when I have occasion to work with this plant. It was once apparently used quite extensively in perfumery.

From Jo Ann Gardner’s The Heirloom Garden, 1992:

The Musk Mallow was grown in colonial gardens, probably for its ease of culture and lovely flowers, fondly remembered from the Old Country, where it grew wild in abundance. Perhaps it was also valued as a herb. “Whosoever takes a spoonful of Mallows,” proclaimed the first-century Roman naturalist Pliny the Elder, “will from that day be cured of all diseases that come to him.” For centuries species in the Mallow Family have been used to soothe inflammations and a variety of complaints. All parts of the Musk Mallow contain a mucilaginous sap suggestive of soothing. The genus name, Malva, comes from the Greek malakos, meaning “softening.”

Unlike other useful plants that were abandoned once they were no longer valued for their healing properties, the Musk Mallow was a favourite ornamental throughout the eighteenth and nineteenth centuries. The elegant white form, ‘Alba’, (was) appreciated in the flower border for (its) beautiful and plentiful shimmering blossoms and accommodating habit.

Malva moschata ‘rosea’ – Musk Mallow ‘Appleblossom’ – Hill Farm, July 2011. Image: HFN

The pink-flowered Musk Mallow, Malva moschata ‘rosea’, is a vigorous plant, making handsome, multi-branching clumps to 4 feet tall and 2 or 3 feet wide. Foliage is bright green, and deeply cut in rounded lobes. Clusters of buds appear in the leaf axils in June, and quickly open into silky-textured, saucer-shaped blooms with prominent bosses of pale yellow stamens. There are different degrees of mauve-tinted “pinkness”, from the pale cultivar ‘Appleblossom’ to the darker ‘Rose Perfection’.

The white-flowered Malva moschata ‘alba’ is a slightly smaller plant, reaching 2 to 3 feet in height. The blooms are white with delicate pink veining, and a blush of pink in the center. ‘White Perfection’ is the cultivar most commonly found.

The basal stems of Musk Mallow can get quite woody by autumn, and mature plants are rather shrub-like in effect. They bloom and bloom and bloom, with new flowers appearing along with the clusters of papery seed pods. If Musk Mallow gets out of hand and starts to lean a bit too heavily on its border neighbours, it can be shorn quite severely in midsummer, and will then cheerfully respond to this rather brutal ‘housekeeping’ by putting out fresh growth and a whole new crop of flowers. It will still be in bloom up to the final hard frost which ushers in winter.

New York gardener Louise Beebe Wilder, one of my very favourite botanical writers, published a book in 1935 entitled What Happens in My Garden, in which she has kind words for the Musk Mallows.

While the Hollyhock is undoubtedly queen of its tribe, some of its cousins are of passing charm. My favorite is the Musk Mallow, and the white Musk Mallow for choice, Malva moschata. They grow about two feet tall, bloom prodigally through July and August and sometimes into September, and the wide flaring blossoms borne in quick succession at the ends of the branches have a fine satin finish that is very attractive. The leaves are cut and cut again, and the plant has a nice bushy, space-filling habit. It was Miss Jekyll who suggested the cool and charming association of white Musk Mallows and steel-blue Eryngiums, one of the most pleasing of summer companionships. And I have found both the pink and white kinds delightful…(T)hese plants are friendly and blossomy when these attributes are most wanted.

Musk Mallow is wonderfully appealing to bees and other pollinators. It also makes a good cut flower. In general, an easy and appealing old-fashioned flower, happy to play a long-blooming supporting role in the perennial border.

Myrrhis odorata – SWEET CICELY

Posted in Herb, Mid Height, Perennial, Plant Portraits, Shade, Spring, White, tagged , , , , , on November 12, 2014|

Myrrhis odorata - Sweet Cicely - Hill Farm - June 2013. Image: HFN

Myrrhis odorata – Sweet Cicely – Hill Farm – June 2013. Image: HFN

Perennial. Zone 3. Apiaceae syn. Umbelliferae. Central Europe, the Pyrenees and the Caucasus. Widely naturalized in Europe and Great Britain. Myrrhis is from the Greek, in reference to the similarity of this plant’s aroma to that of the sap of the tropical myrrh tree (Commiphora species), much valued for perfumery. (The true myrrh was traditionally one of the costly gifts presented to the Baby Jesus by the Three Wise Men.) Odorata is from the Latin, “scented”.

I have never seen this lovely herb for sale in commercial nurseries in our area, which is why I was so thrilled to find it in a small roadside nursery near Bella Coola way back in 1998. I tucked it into a corner of the flower border, where it has maintained itself ever since, forming quite a vigorous colony of ferny, liquorice-scented foliage accented by lacy umbels of pure white blooms in spring.

I’ve transplanted seedlings – very carefully, for Myrrhis odorata has a long, brittle tap root – into various shady spots, where it happily settles in and adds its delicate leafiness to the general green tapestry effect. The blooms are followed by upright clusters of huge, light green seeds, which slowly darken to glossy black.

Where happy the plant reaches a substantial size, easily 2 feet or taller, and eventually several feet wide as the foliage expands through spring into early summer. Once blooming is finished, the plant may be shorn back to the ground, where it will re-sprout with renewed vigour and provide a pleasant backdrop for later-blooming flowers.

The texture of the foliage is delicately downy – it feels as soft as it looks. I have occasionally added it to cut flower bouquets for its ferny effect, but it isn’t really happy once cut, so I now mostly enjoy it in the garden.

Sweet Cicely has a long history of use as an herb, being strongly anise (licorice-like) scented in all of its parts, and having a very sweet flavour. It is one of the benign “innocent herbs” – edible in all of its parts, and free of potentially harmful components.

Myrrhis odorata will thrive in the sunny mixed perennial border, as it enjoys fertile soil and summer moisture. It can also be placed in quite deep shade, and, if encouraged to self-sow, will spread to fill in the area under high-pruned shrubs and trees.

I have not found Sweet Cicely to be particularly weedy – seedlings are easy to identify and easily plucked out – but it is a persistent plant once established (that taproot goes a long way down), so consider its siting carefully. Mature plants do not move well, so container grown starts and young seedlings are your best bet for bringing it into your own garden or for spreading it around.

Myrrhis odorata – Sweet Cicely – Hill Farm – June 2014. Image: HFN

Maud Grieve’s massive reference book, A Modern Herbal, first published in 1931, has these notes on Myrrhis odorata:

It is a native of Great Britain, a perennial with a thick root and very aromatic foliage, on account of which it was used in former days as a salad herb, or boiled, when the root, leaves, and seed were all used. The leaves are very large, somewhat downy beneath, and have a flavour rather like Anise, with a scent like Lovage. The first shoots consist of an almost triangular, lacey leaf, with a simple wing curving up from each side of its root. The stem grows from 2 to 3 feet high, bearing many leaves, and white flowers in early summer appear in compound umbels. In appearance it is rather like Hemlock, but is of a fresher green colour. The fruit is remarkably large, an inch long, dark brown, and fully flavoured. The leaves taste as if sugar had been sprinkled over them.

It is probable that it is not truly a wild plant, as it is usually found near houses, where it may very probably be cultivated in the garden. Sweet Cicely is very attractive to bees; in the north of England it is said that the seeds are used to polish and scent oak floors and furniture. In Germany they are still very generally used in cookery. The old herbalists describe the plant as ‘so harmless you cannot use it amiss.’ The roots were supposed to be not only excellent in a salad, but when boiled and eaten with oil and vinegar, to be ‘very good for old people that are dull and without courage; it rejoiceth and comforteth the heart and increaseth their lust and strength.’

Monarda fistulosa – WILD BERGAMOT, LILAC BEE BALM

Posted in Full Sun, Mid Height, Perennial, Purple, Summer, Xeriscape, tagged , , , , , , , , on November 4, 2014| 1 Comment »

Monarda fistulosa – Lilac Bee Balm – growing in the wild – July 2014 – Soda Creek, B.C. I see three insect visitors on this one small flower cluster, including a wild bumblebee (Bombus sp.) – these plants were a-buzz with nectar gatherers the hot summer day these photos were taken. Image: HFN

Perennial. Zone 2. Lamiaceae. Native to North America, including the Okanagan, Thompson-Nicola, and Cariboo-Chilcotin regions of B.C.  A.k.a. HORSEMINT, PURPLE BEE BALM. Monarda was the name given to this species by Linnaeus, after the Spanish botanist Nicolas Monardes, who published a well-regarded treatise in 1574 describing the plants of the New World, though Monardes himself never travelled there, and worked from specimens collected by others. The Latin species name fistulosa = “hollow, pipe-like’, in reference to the tubular structure of the individual flowers.

This is a somewhat variable but always lovely species native to prairie and foothills ecosystems. It grows wild in the Cariboo-Chilcotin on dry hillsides and on the fringes of Douglas fir forest throughout the Fraser River corridor at least as far north as Marguerite.

Monarda fistulosa - Wild Bergamot - Soda Creek, B.C. - July 2014. Image: HFN

Monarda fistulosa – Wild Bergamot – Soda Creek, B.C. – July 2014. Image: HFN

2014 was a stellar summer in our area for Wild Bergamot and many other wildflowers. The hillsides around Soda Creek were ablaze with purple for weeks in June and July, as the bloom times of the aster-like native Showy Fleabane, Erigeron speciosus, overlapped with that of the Monarda.

The First Nations peoples of the areas where Monarda fistulosa grows thought very highly of it as a useful plant. The strongly aromatic foliage, which is high in the compound thymol, was used in cooking and medicine, as a tea, insect repellant and smudge ingredient. European settlers appreciated it as well, in particular using it as a tea ingredient; the “bergamot” of the common name refers to the similarity of this species aroma and flavour to that of the Bergamot Orange (Citrus bergamia) essential oil which gives Earl Grey Tea its distinctive character.

Wild Bergamot was adopted into domestic gardens as soon as specimens made it back to Europe and England, for its usefulness as well as its considerable beauty. Monarda fistulosa has been widely used in hybridization with others of the genus, in particular the showy Scarlet Beebalm, Monarda didyma, to produce a number of stellar Beebalm cultivars, such as ‘Violet Queen’, and the wonderful ‘Blue Stocking’.

Monarda fistulosa is a grand garden plant in our area, and particularly useful in xeriscape plantings, though it also appreciates the richer, moister climate of the traditional perennial border.

Sturdy clumps of 24 to 36 inch tall, square-sided, leafy stems are topped by large whorled clusters of pale lilac-purple “dragon’s head” blooms in summer. Shades range from almost-white palest lilac to a rich rosy purple; the norm is the shade shown in these images.

The common name Bee Balm is very apt; these plants are highly attractive to bees of all sorts, to butterflies, and to hummingbirds. The tubular blooms are rich in nectar, and on sunny days the clusters are busy places, being “worked” flower by flower neatly around the floral ring by various foragers.

The Herb Society of America chose Wild Bergamot, Monarda fisulosa, as its Notable Native of 2013.

Sun, average conditions. Very drought tolerant once established.

This species can be afflicted by the fungal powdery mildew in very dry years; cut back affected plants and dispose of the clippings away from the garden – do not compost – to reduce its future occurrence. Occasional supplemental watering in very dry years, even in your drought-resistant xeriscape plantings, will strengthen plants and prevent such problems from occurring.

Achillea millefolium v. rubra – RED-FLOWERED YARROW

Posted in Full Sun, Mid Height, Perennial, Pink, Plant Portraits, Summer, Xeriscape, tagged , , , , , on November 2, 2014|

Perennial. Zone 1. Asteraceae. Achillea millefolium is native to the Northern Hemisphere, and is found in Europe, Asia, and North America. Common names are numerous, including MILFOIL, BLOODWORT, SOLDIER’S WOUNDWORT, and SANGUINARY, most in reference to the plant’s reputation as a wound-healing herb.

The common name Yarrow comes from the Anglo-Saxon gearwe, “to make healthy”, in reference to the plant’s long use as a medicinal herb.

Achillea is after the Greek mythic hero Achilles, who was reputed to have been tutored in herbal lore by Cheiron the Centaur. This herb has long been used as a “wound herb”, as it has blood-stopping and pain-killing properties. (Handy for a warrior-hero to know the use of, one would agree!)

Millefolium = “thousand leaved”, for the finely cut, ferny foliage.

The species form found most commonly in the wild, Achillea millefolium, has pure white blooms, but there is an Appalachian strain, A. m. var. rubra, which has been “improved”, and which has contributed its rich colour to numerous garden cultivars.

Red-Flowered Yarrow has been a common garden plant for at least a century in North America. The Red Yarrows produce many flat-topped heads – corymbes – of small, ash-grey-eyed, rosy pink to deep red blooms on sturdy 18 to 24 inch tall stems in summer. The bloom time is long, and cropping off the spent flower heads will keep more coming.

Foliage is deep green, beautifully ferny, and pungently aromatic when crushed.

All of the Red Yarrow cultivars are very easy and dependable. The plant spreads from a central clump by creeping, rooted stems, but it is well behaved and easy to curb. It is also decently drought tolerant, so worth consideration in xeriscaping. These plants will get taller and appear more lush with good soil and supplemental summer moisture.

The Red Yarrows are very good cut flowers and everlastings if cut in the early bloom stage.

Cultivars of note are:

‘CASSIS’  – Many corymbes of small, intensely burgundy red flowers on 18-inch tall stems in summer. Cut as everlastings these dry to a rich black currant colour, hence the cultivar name. Very easy and dependable. This cultivar was a European Fleuroselect Winner  in 2002, chosen for garden merit.

‘CERISE QUEEN’ – This cultivar been around for quite a few years. It has corymbes of cherry red blooms which fade through stages to a washed-out almost-white. It has a long bloom time, spreads steadily but not invasively, and is essentially as tough as nails. 12 to 24 inches tall, depending on richness of soil and amount of moisture.

You may also come across ‘RED VELVET’, ‘STRAWBERRY SEDUCTION’, ‘SUMMERWINE’, and several others. All are fairly similar in habit, though degree of redness will vary. The red flowers of all of these will fade as the bloom season progresses, ending up a greyed pink-white. As mentioned earlier, clipping these off will keep the plants looking fresh, and will usually trigger re-bloom.

Average soil and moisture, sun to light shade. Drought tolerant once established.

Aquilegia alpina – ALPINE COLUMBINE

Aquilegia alpina – Alpine Columbine – Chilliwack, B.C. – June 2013. Image: HFN

Perennial. Zone 2. Ranunculaceae. From the European Alps and Apennines.

This is a grand, very long-blooming species, native to European mountain meadows and open forests. It has been grown in gardens for centuries, and has been much used in Aquilegia hybridization.

Large, short-spurred, dusky violet-blue flowers in profusion top 12 to 18 inch tall plants from mid-spring well into summer. A tidy plant, hardy and adaptable. It will self sow, and will cross pollinate with other Aquilegias growing nearby, so your seedlings will always be something of a surprise as to colour and form.

Aquilegia alpine - Vancouver, June 2011. Image: HFN

Aquilegia alpina – Vancouver, June 2011. Image: HFN

It is noted by Aquilegia authority Robert Nold in his definitive 2003 monograph, Columbines: Aquilegia, Paraquilegia, and Semiaquilegia, that Aquilegia alpina in its pure form is seldom to be had in the plant trade due to the general promiscuity of this genus, to whit: “As with many columbines, the genetic purity seems to have been diluted by cultivation through the centuries…”

Plants I have grown from reliably-sourced seed labelled “alpina” have always shown a strong similarity in colour and habit; the species (or at least the cultivated, evolved form of the species) seems to exist in a fairly stable type.

It would be interesting to grow out some wild-collected seed from Aquilegia alpina’s native habitat to compare with the cultivated strain; perhaps I will request some from this fall’s collectors’ seed lists and see what we come up with.

Sun to shade, good soil and moisture.

Phlomis tuberosa – TUBEROUS JERUSALEM SAGE

Posted in Full Sun, Mid Height, Perennial, Pink, Plant Portraits, Summer, Xeriscape, tagged , , , , on October 30, 2014|

Phlomis tuberosa - Hill Farm, June 2011. Image: HFN

Phlomis tuberosa – Hill Farm, June 2011. Apologies for the poor image quality, as it was taken in the evening, after rain. I have some better photos somewhere, from the pre-digital camera era, but this shall have to suffice for now. Image: HFN

Perennial. Zone 2. Lamiaceae, formerly Labiatae. Eastern Europe, Turkey, Iran, Siberia. A plant of steppes and dry meadows.

The quirky Phlomis genus has always rather fascinated me. Without any real hope of having them succeed, I’ve labouriously grown from hard-to-germinate seed and promptly lost their first winters the beautiful yellow-flowered Phlomis fruticosa (Jerusalem Sage) and P. russeliana (Turkish Sage). “Root hardy to Zone 5,” say those who should know, but sadly that doesn’t seem to be good enough. But I will doubtless try again, for I’ve just been through the Mediterranean section of Van Dusen Garden in Vancouver, and even in its autumn disarray Phlomis fruticosa looks darned good, all velvet foliage and intricate seed heads.

Phlomis fruticosa - Jerusalem Sage - a true Mediterranean plant, shrubby and silver-leaved. In Vancouver's mild climate it thrives in a raised bed at Van Dusen Garden. (And check out the flourishing Bay Laurel behind it! Oh, envy...) October, 2014. Image: HFN

Phlomis fruticosa – Jerusalem Sage – a true Mediterranean plant, shrubby and silver-leaved. In Vancouver’s mild climate it thrives in a raised bed at Van Dusen Garden. (And check out the flourishing Bay Laurel behind it! Oh, grounds for some serious plant envy right here in this small image…) October, 2014. Image: HFN

So I turned my attention to the only other readily available species on the seed lists I had access to, the pink-flowered Phlomis tuberosa. A few seeds sprouted, and quickly grew into sturdy young plants, with dark green, elongated-heart-shaped foliage. Planted out, these survived their first winter with vigour, re-sprouting in spring in much more substantial clumps than I had anticipated. By year three, obviously happy in their Cariboo home, long bloom stalks appeared in late May, with whorls of intriguing buds, each sporting a pair of elongated leaves at the base. The buds eventually popped open into the most fascinating small, mauve pink, delicately fringed dragon’s head flowers. Not as spectacular as the much larger blooms of my yearned-for Phlomis fruticosa, but charming nonetheless.

Phlomis tuberosa has now been in my garden for almost two decades. It keeps getting moved around, and I’ve lost track of the many places I’ve rather heartlessly plunked it down in during our endless plant shuffles, for I found out early on that it was an agreeable sort of creature, easy to transplant and happy almost anywhere.

Phlomis tuberosa is a slender sort of plant. It will reach 3 or 4 feet tall in bloom stage, with numerous wiry, angular-sided stems arising from a tidy basal rosette perhaps a foot or so in diameter. Foliage is excellent and looks good spring to fall, being glossy, dark green, and roughly heart-shaped.

Whorls – technically “verticillasters” – of tiny, tubular, deliciously fringed pale purple-pink flowers in tiers on the slender but sturdy red-blushed stems appear in late spring. Each “ring” of blooms in the cluster opens at the same time, and the quiet show goes on through June and often into July, after which the developing seed heads may either be clipped off or left for garden interest.

Phlomis tuberosa has never needed staking, despite its height. The roots are quite fascinating, as you will find if you have reason to transplant a mature plant. Hanging from the ropy root clusters are many perfectly round tubers, like tiny potatoes. These are apparently quite edible – though please don’t experiment only on my say-so! – and were used as food by indigenous peoples in the plant’s native ranges.

Those storage roots may also explain Phlomis tuberosa’s wonderful adaptability. Established plants can take severe drought, and hold their own well among encroaching grasses, which has led to its use as a flowering accent in the famous “prairie borders” of such influential landscape designers as Holland’s Piet Oudolf. A potentially useful xeriscape plant for the Cariboo.

Though you may see Phlomis tuberosa rated at a conservative Zone 6 or so in much literature, rest assured that it is a lot hardier than that, and, if planted in the spring and given a growing season to get its roots down, can handle Zone 2 conditions without any trouble whatsoever.

This is not a particularly showy plant, but it is happily interesting, and I hope to continue growing it for many years to come. I’ve just pulled my own much-abused plants out of a border where they were being overshadowed by a massive Joe-Pye Weed, and have plunked them in the nursery rows in the garden to await a new placement come spring. I’m not quite sure where they will end up this time around, but I do know that they are “keepers”.

Bees and butterflies love Phlomis tuberosa, too. It may be grown in sun to light shade, and can handle any sort of soil. Good with sedums and ornamental grasses.

You may see Phlomis tuberosa listed with a cultivar name. A commonly seen tag is ‘Bronze Flamingo’, though as far as I have been able to discover this is merely a plant trade invention to up the appeal of the rather ho-hum species name. If visiting specialty plant nurseries on the coast, you may come across a cultivar named ‘Amazone’, which is reported to be an improvement of the species type, being larger in all of its parts and much taller, apparently to 7 feet.

Lysimachia punctata – DOTTED LOOSESTRIFE

Perennial. Zone 2. Myrsinaceae, formerly Primulaceae. A.k.a. YELLOW LOOSESTRIFE, GOLDEN STARFLOWER. Austria, Italy, and east to Turkey.

This rather romping species is native to Europe, and has been grown in gardens for centuries. It was thought to have medicinal properties, being used as a wound herb to stop bleeding, and also to repel insects. Now we grow it strictly for ornament, for its adaptability and the summer beauty of its bright yellow star flowers.

Looking at the vivid yellow, unmarked flowers, you may wonder why Dotted Loosestrife is a common name, but if you look very closely at the undersides of the leave, you will see the tiny dark oil glands which led to Linnaeus choosing punctata – in Latin, “a point” – as its specific designation.

This plant is quite a tidy clump former its first few years, but keep an eye on it, as it will suddenly decide it needs more ground and it will expand outwards in all directions, though not by runners, merely by shouldering aside less robust neighbours. Lysimachia punctata is a well-respected garden plant, but it is not exactly what one would call shy, so you will want to site it appropriately.

Though Dotted Loosestrife is decidedly a moisture lover, I have had great success with it in a rather dry, neglected bed. It shares its space with a huge clump of ribbon grass (Phalaris arundinacea picta), ‘Europa’ tawny daylily (Hemerocallis flava), and a perennial sunflower, Heliopsis helianthoides, all of which are equally vigorous and have reached a kind of boundary stalemate. This combination has been working nicely for over ten years, though I do occasionally steal a few divisions to put elsewhere or to sell. I did initially grow it in a moist, fertile, newly prepared bed, but it was much too happy there and overran some more delicately precious plants, hence its relative exile to its present location.

Lysimachia punctata grows to about 2 feet tall and wide in its present place; I suspect it would be even taller with more care. It’s a beautiful plant when in bloom, and something I particularly enjoy is its habit of shedding spent flowers like a cloud of star-shaped confetti all over the ground. It blooms for weeks and weeks, mid June right through July and into August most years, and even after flowering the foliage stays handsome, though a few leaves will brown a bit. It is also an excellent cutflower, though it does shed flowers from the bottom up.

There are two variegated varieties which are now in cultivation, both developed from spontaneous colour breaks in plantings of Lysimachia punctata in England.

The first is a white-edged sport called ‘Alexander’, or sometimes ‘Alexander’s’, named after the late husband of its discoverer, Pauline Alexander. First identified in 1990, the plant was patented in 1998, after nursery trials proved its colour stability and growth trait predictability.

‘Alexander’ is much slower growing than its mother species, and needs a bit of nurturing and a good moist soil at least the first few years. It has extremely appealing pink-blushed emerging growth in spring, very exotic! If this cultivar has a fault it is that the variegation causes puckering along much of the foliage; “purse-stringing”, as it is called. This puckering looks rather like disease or insect damage at first glance, and may be worrisome if you’re not aware that this is a varietal characteristic.

Whatever genetic mutation was at work was not quite finished yet, for in 1998 another colour break was observed, this time in a test planting of ‘Alexander’ at Walburton Nursery in England. The leaf edges were golden, instead of white, and without the drawstring puckering which marked ‘Alexander’. ‘Golden Alexander’ was separated out, reproduced, and patented as a separate variety in 2003.

Both ‘Alexander’ and ‘Golden Alexander’ are hardy and suitable for the Cariboo-Chilcotin. They are not as vigorous as the green-leafed species, and require some care to ensure they reach full potential, but their bright colour is very appealing and they are worth growing for their strong curiousity value.

Something to watch out for in both of these cultivars is their strong tendency to revert to their all-green state. Vigilantly nip out any green shoots appearing in your colony, as these will quickly take over if allowed to remain.

Lysimachia punctata in all its colour variations thrives in full sun to part shade. It can happily be grown very moist, but accepts drier conditions with aplomb. It appreciates average garden soil – don’t grow it too rich. In general, a tough and trouble free species.
