Sporadic in grassland, flowerheads commonly eaten by Mule Deer. A sparse invader. The sap is a milky latex which can cause burns or allergic reactions.
Edible: roots of first year plants make an excellent cooked vegetable, with flavor like oysters, parsnips, or gobo. They can be garden-grown, in which case they should not be allowed to flower and go to seed!
