Cirsium suffultum (common name: tsukushi-azami)
Propagation: Seed - sow early spring or autumn in situ. Germination usually takes place within 2 - 8 weeks at 20°c[1].
Division in spring or autumn.
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 could succeed outdoors at least in the milder 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[2].
Range: E. Asia - S. Japan.
Habitat: In sunny grasslands of temperate zones at elevations of 600 - 1700 metres[3].
Edibility: Root - cooked[4]. 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].
Usage: The seed of all species of thistles yields a good oil by expression[5]. No details of potential yields etc are given[K].
Pollinators: Insects
Soil: Can grow in light, medium, and heavy soils.
Flower Type: Hermaphrodite
