General Information

Oxytropis tragacanthoides is a strongly branching spherical dwarf shrub, forming "cushions" up to 30 cm in diameter, with thick hard dichasially branching branches, pricklyspiny from indurate petioles[, ].
One of the few woody plants in the regions where it grows, this species is often used for fuel[].

Known Hazards

We have no information for this species, but several members of this genus are known to be potentially toxic, particularly to grazing animals.
Some members of the genus are known to contain the indolizidine alkaloid 'swainsonine'. Chronic intoxication with this alkaloid causes a variety of neurological disorders in grazing animals along with reduced appetite which can lead to weight loss and cessation of reproductive ability. Swainsonine has also been found to have potential for use in anti-cancer drug treatments.
In some species, other alkaloids are suspected of causing toxicity.
In addition, some members of the genus have been reported to accumulate selenium - although this is an essential trace element it can be toxic in higher doses. Signs and symptoms of selenium toxicity include a garlic odour on the breath, gastrointestinal disorders, hair loss, sloughing of nails, fatigue, irritability, and neurological damage - in extreme cases it can result in death.

Cultivation Details

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[].
We have seen no specific information for this species, but most members of this genus have 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.

Other Uses

Although very small and prickly, this species is one of the few woody plants in many parts of its range anf is traditionally used as fuel in the republics of Tyva and Altai of the Russian Federation as well as in Mongolia[].

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 deep pots in a cold greenhouse or cold frame, and plant them out the following spring[].
