Cirsium edule (common name: edible thistle)
Propagation: Seed - sow early spring or autumn in situ. Germination usually takes place within 2 - 8 weeks at 20°c.
Cultivation: An easily grown plant, succeeding in any ordinary garden soil in a sunny position[1].
A monocarpic species, it grows for a number of years without flowering but then dies after flowering[2].
Range: Western N. America - southwards from Canada.
Habitat: Wet meadows and open woods in mountains[2].
Edibility: Root - cooked[3][4][5][6]. 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].
Young stems - peeled and eaten raw[7][8][3][4]. Soft and sweet[5], they are considered to be a luxury food[6].
Young shoots - raw or cooked as greens[6]. Harvested in spring[6].
Usage: The seed of all species of thistles yields a good oil by expression[9]. No details of potential yields etc are given[K].
Pollinators: Bees, flies, lepidoptera, beetles, self
Soil: Can grow in light, medium, and heavy soils.
Seed Ripens: Late Summer-Early Fall
Flower Type: Hermaphrodite
