Oxytropis lambertii has 0 edible uses listed

Uses

Toxic parts

The plant is toxic to cattle, does it concentrate selenium from the soil[1]? Horses that eat this plant become very difficult to handle and can imagine that a pebble is a large rock or that a wide stream is only narrow[2]. The plant contains toxins, possibly indolizidine alkaloids. The toxin can accumulate in the body and causes trembling, high excitability, paralysis and death[3].

Edible uses

Notes

Root[4][5][6]. The whole plant, including the roots, is eaten by horses[7]. No further details are given, but caution is advised, see notes at top of page. Used to make a mush, or parched and used for food[7]. This report is probably referring to the seeds[K].

Propagation

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 the greenhouse and plant them out the following spring[1]. Division in spring[8]. Since the plant resents root disturbance this might not be a good idea.

Cultivation

Easily grown in an ordinary garden soil but prefers a sandy loam[8]. Best in a deep, gritty perfectly drained soil in full sun[1]. Strongly resents winter wet[1].

A very ornamental[8] and variable plant[9]. Plants resent root disturbance and so should be pot-grown then and planted out into their permanent positions whilst still small[1].

This species has a symbiotic relationship with certain soil bacteria called Rhizobia. These bacteria form nodules on the roots of the plants and fix atmospheric nitrogen, plants may fail to flourish due to the absence of the appropriate Rhizobium species. Some of the nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[1].
