Trachystemon orientalis



Trachystemon orientalis, commonly known as early-flowering borage, is a tough, rhizomatous, shade-loving, weed-smothering, perennial ground cover that is native from Bulgaria to the Caucasus and Turkey. Pendant, borage-like, white-throated, bluish-purple flowers (each to 1/2” wide) bloom in early spring (March-April) in loose-branched panicles located atop branched, hairy, pink-tinted flowering stems rising to 18” tall. Flowers bloom at a time when the foliage is just beginning to develop. Flowers have tubular corollas with five spreading to slightly reflexed petals. Large, coarsely-textured, long-petioled, heart-shaped, bristly-hairy, overlapping, medium to dark green basal leaves (each to 12” long) typically mature to full size after flowering has finished to form a dense but attractive foliage mat rising to 18” tall but spreading over time to 24” wide or more.
How to Care for the Plant
 - Water - The plant needs regular watering while it`s establishing. After that, watering can be reduced to let the soil dry out between waterings. It survives dry shade once established, although in prolonged very dry conditions, the leaves may collapse. 
 - Fertilizer - It does not require feeding; avoid soil rich in nitrogen or plants may not bloom. Fertilize with compost tea or a dilute solution of fish emulsion to give flowering plants a boost. 
 - Sunlight - It tolerates full sun, but usually performs best in sun-dappled part shade. 
 - Soil - It is tolerant of a wide range of soils. Mulch around the plant to keep foliage off of the ground where it may rot. 
 - Temperature - This plant can be grown in the areas with the lowest winter temperatures of −20.6°C (−5°F).
