Edible Uses
Edible Parts: Oil Root Shoots Stem
Edible Uses: Oil
Root - cooked[95, 105, 161, 257]. 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[46, 61, 95, 105]. Soft and sweet[161], they are considered to be a luxury food[257]. Young shoots - raw or cooked as greens[257]. Harvested in spring[257].
