A florist’s dream, Veronicastrum sibiricum adds vertical interest to indoor floral arrangements.Slender, tapered candelabra-like flowerheads consist of an abundance of densely packed lavender-lilac, tubular blooms. Held on strong, wiry stems they point upwards and are often seen planted in RHS show gardens, weaving amongst grasses and other perennials, waving in the breeze. Lush green, lance-shaped, toothed leaves are produced in whorls around each stem. A magnet for bees and other pollinators and known commonly as the ‘Siberian blackroot’ and smaller than its relative Veronicastrum virginicum both are native to meadows and grassy slopes of East Asia. Named after Saint Veronica who is said to have given Jesus her veil to wipe his forehead while carrying his cross, and astrum which means star.Veronicastrum sibiricum prefers to be grown in moist soil, even on the edge of a bog garden, in sun or partial shade. An herbaceous perennial, hardy to -20C, which will become dormant over winter.
