Cultivation

We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it should succeed outdoors in many parts of this country. The plant is a short-lived perennial. The following notes are based on the general needs of the genus. An easily grown plant, succeeding in any ordinary garden soil in a sunny position.

Propagation

Seed - sow early spring or autumn in situ. Germination usually takes place within 2 - 8 weeks at 20°c.

Edible uses

Root - cooked. The root is likely to be rich in inulin, a starch that cannot be digested by humans. This starch thus passes straight through the digestive system and, in some people, ferments to produce flatulence[K]. Stem. No more details are given.

Medicinal uses

The plant has been used to treat wounds, cuts and sores.

Material uses

The seed of all species of thistles yields a good oil by expression. No details of potential yields etc are given[K].

Habitat

Dry stony slopes, 3000 - 3500 metres in California.
