Perennial. Zone 4. Labiatae. Central and southern Russia, Romania, most notably in the Transylvanian Alps.

We are fortunate in the Cariboo in regard to our many summer perennial plant choices. The Salvias in particular appreciate our generally hot and dry summer season, and this handsome species puts on a grand show in July and August.

Large, dusky indigo-blue-violet flowers, “dragon head” shaped as is typical of all members of the Salvia genus (the Sage Family), are produced in loose whorls on multi-branching 18 to 24 inch tall bloom spikes. These arise from substantial rosettes of long, prettily wrinkled, rather hairy, deep green leaves. Foliage is slightly aromatic when touched, but is much less pungent than many of its relatives. A vigorous plant can be 2 feet or more in diameter, and rather sprawling in habit. Great on a slope, or under high-pruned, not-too-dense shrubs such as roses or spirea.

Transylvanian Sage blooms for a long period in summer, and, if spent spikes are clipped off occasionally, well into autumn. Grand for a sunny border, and drought tolerant enough to be a good xeriscape plant.

Plant it under roses in the traditional border, or with sedums and ornamental mulleins in the dry border. The colour harmonizes marvellously well with almost anything, and can be used for gentle compliment of other pastel shades or to set off hotter colours.

I have found that Salvia transylvanica overwinters extremely well as a young plant, but sometimes tends to bloom itself out, so I do not consider it particularly long lived. Allow it to set seed, and you will find enough babies to keep it going in your garden. These transplant well if you move them at a young age. Older plants should be left undisturbed; I wouldn’t recommend transplanting or dividing.

Sun is best, though very light shade is acceptable. Average to well drained soil; average fertility; average watering. Nicely drought tolerant once established.
