If looking for a perennial with interesting architecture that would look great or even dominant among shrubs or trees, perhaps could be a substitute for a shrub in places where there is not enough space, culver’s root might be the one for you. This genus has two species, each of them is named after its origin: Virginian and Siberian. They are very similar and differ mostly in flower colour and size in maturity. Formerly named as veronica (speedwell) it was decided that culver’s root is so unique that it deserves its genus.Virginian culver’s root produces several whorls of chaste-tree-like, narrowly lance-shaped, mid to dark green leaves. They may resemble cannabis. In early summer the tips of the stems begin producing flower buds composed in long spikes, botanically more correctly classified as terminal racemes, opening in into small flowers in early July.
Description of the plant:
Apollo is a variety with pale blue flowers where the inflorescences are produced well above foliage level. The plant has more compact habit compared to the species and it stems seldom exceed 1m tall. Individual flowers are tubular and decorated with long white stamens with beige anthers owing to which they look hairy. Culver’s root will grow in evenly moist, fertile soil in full sun or with some shade during the day. It requires no maintenance whatsoever except for removing dead stems in early spring and some extra watering in very dry summers. It is hardy to about -40°C (USDA zone 3).
