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 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[
Young leaves - cooked[
]. Added to soups or fried[
Root - cooked[
]. The roots are slender with scarcely developed rhizomes[
]. They are scraped into pieces, steeped in water and preserved in miso[
]. 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[
The flower heads are fried or used in salads[
The seed of all species of thistles yields a good oil by expression[
]. No details of potential yields etc are given[
Seed - sow early spring or autumn in situ. Germination usually takes place within 2 - 8 weeks at 20°c[
