Culver's root is an attractive perennial with an elegant, upright habit.
Veronicastrum sibricum is native to the mountain meadows and plains of East Asia (Japan, Korea, northern China, eastern Siberia and Sakhalin Island); in summer time it produces long flowering spikes borne on stems that can grow to 180 cm in height.
In the garden, it's a great architectural feature that is very long lived.
- In a mixed border its powerful verticality works well at the back of a bed.
- In a natural meadow setting we like to combine Veronicastrum sibiricum with light grasses (Calamagrostis, Eragrostis).
- Come wintertime, its tall brown stems remain attractive mixed in with the dried inflorescences of Helenium, Echinacea or Sanguisorba.
For forest edges, cottage gardens, meadows. The flowers are very attractive to our foraging friends, the butterflies, bees and company!
Easy to grow in the sun (not scorching) or light shade in good, fertile, constantly moist garden soil. Hardiness: 20 °C
- cut back the plant at the end of winter;
