Description
A perennial thistle growing to 1.5 m tall. Flowers July to August with seeds ripening August to September. Hermaphroditic and self-fertile, pollinated by bees, flies, moths, butterflies, and beetles. Adapts to light sandy, medium loamy, and heavy clay soils with mildly acid to mildly alkaline pH. Requires full sun and prefers moist soil.
Edible Uses
The root is edible cooked, though it is slender with scarcely developed rhizomes. It is likely to be rich in inulin, a starch that cannot be digested by humans; it passes straight through the digestive system and, in some people, ferments to produce flatulence. Young plants can also be eaten cooked.
Medicinal Uses
None known
Distribution
It is a temperate plant.
Where It Grows
Asia, Japan,
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 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
Sow seed in early spring or autumn in situ. Germination usually takes place within 2–8 weeks at 20°C. Can also be propagated by division in spring or autumn.
Other Uses
The seed, as with all thistle species, yields a good oil by expression. No details of potential yields are given.
Notes
There are about 150-250 Cirsium species. They grow in temperate regions.
