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.

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.

Mirabilis nyctaginea – WILD FOUR-O’CLOCKS

Wild Four-O-Clocks - Mirabilis nyctaginea. Spences Bridge, B.C. May 30, 2014.

Perennial. Zone 6, possibly colder. Nyctaginaceae. A.k.a. Heart-Leaved Four-O’Clock, Umbrellawort. Native to the Great Plains of the United States, as well as southern regions of Manitoba, Saskatchewan and Ontario. Isolated introduced populations found throughout B.C., Alberta and Quebec.

On a recent road trip, heading through the arid rangelands and rolling hills south of Cache Creek and following the Thompson River’s deeply carved valley as it heads towards its spectacular rendezvous with the Fraser at Lytton, my attention was caught by several tall clumps of lush, dark green foliage, showing clusters of small but vivid magenta-pink blooms. Pulling over in a wide spot on the road, I looped back to take a closer look.

An initial examination of the flower structure and foliage gave me an “Aha!” moment. Could this possibly be wild four-o’clocks? It wasn’t in any of the wildflower field guides I had along, nor, when back home, in my trusty and comprehensive Lewis J. Clark’s Wild Flowers of British Columbia, but an internet search yielded an immediate confirmation.

Plant habit is eye-catching, in this case because of its unexpectedly lush greenness set against a background of silver-green sagebrush and bunchgrass-tufted hills.

My online research yielded these details.

The plants grow in vigorous clumps from 1 to 3 feet tall (these were about 2 feet tall), with broad, heart-shaped, opposite leaves clasping the angle-sided stems. Flower clusters show green bracts at the bases of the tubular flowers, which are of a bright magenta pink. Stamens are also magenta, tipped with yellow pollen. After flowering, the bracts enlarge into a papery “umbrella” centered by a cluster of large, rather hairy nutlet-type seed. These bracts then act as parachutes during the seed dispersion stage.

The plant forms a large, tuberous tap-root, which extends a foot or more into the soil, allowing the plant to thrive in arid conditions. This root is what has led this plant to be classified as a weed-of-concern in some regions, as it is very hard to eradicate once established, being highly herbicide resistant, and able to resprout from root fragments left in the soil after pulling. (And of course the wind-dispersed seeds would also be a major factor in its ability to spread, especially in areas of disturbed soil.)

The sweet-tasting roots of this plant were used by indigenous peoples as a poultice for skin ailments and burns, and as a medicinal tea to expel worms, and to treat fevers and bladder complaints. Though pigs apparently dig up and eat the roots with great relish – they are recommended for eradication in agricultural infestations – there is some speculation that Mirabilis nyctaginea may contain some mildly toxic alkaloids, so experimentation with herbal use is not advised.

I suspect that this plant would not be winter hardy in the Cariboo-Chilcotin, but it might well succeed as an annual, as its domestic relative, the lovely and fragrant Mirabilis jalapa (the commonly grown garden flower Four-O’Clocks, or Marvel-of-Peru) blooms generously as a summer-flowering annual, and forms a similar fleshy root which does not withstand freezing soil.

While decidedly pretty in a low-key way, Mirabilis nyctaginea is not particularly showy, and reports of its “weedy” tendencies would make me cautious to recommend this plant, though it might be an interesting addition to a wildflower planting if one is feeling adventurous, and is prepared to remove seedheads before they can disperse. Seed is often available for this plant through botanical seed exchanges, and commercially through some specialist native plant seed houses.
