Oxytropis nigrescens is a loosely-matted, clump-forming herbaceous perennial plant growing from a branched caudex; it can grow up to 8cm tall.
The plant is harvested from the wild for local use as a food.
E. Asia - Russia (Siberia); N. America - Alaska, Yukon, Northwest Territory, northern British Colombia
Rocky ledges, often among lichen and mosses, growing from Arctic shores and islands to montane regions.
Oxytropis species generally grow best in a very sunny position in a deep, well-drained, sandy or gritty soil[
]. Species with woolly leaves greatly resent winter wet[200[.
Many species in this genus are suitable as ornamentals, valued for their clusters of flowers and their attractive foliage. However, species often fail in cultivation, often because of a lack of an appropriate Rhizobium bacterium[
Members of this genus are generally resentful of root disturbance and, if the seed is not sown in situ, then seedlings need to be planted into their permanent positions as soon as possible[
This species has a symbiotic relationship with certain soil bacteria; these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[
]. No further details are given, but caution is advised - see notes above on toxicity.
Pre-soak the seed for 24 hours in warm water and then sow in a greenhouse in early spring. Prick out the seedlings into individual pots as soon as the cotyledons emerge in order to avoid damage to the root. Grow them on in deep pots in a cold greenhouse or cold frame, and plant them out the following spring[
