lobed 20 cm leaves. The leaves and stems are pale blue green. The 7-10 cm flowers bloom from late spring into summer. Each flower has 4-6 very thin translucent white petals that flutter in the wind and a dense center cluster of yellow stamens. In late summer the plant has sparsely prickly seed capsules with small black seeds. Broken or nicked stems produce thick orange-yellow sap. It has a large taproot for accessing water in freely draining soils. All parts of the plant are poisonous. Because of its prickly defenses, and acrid taste from its poisons, grazing animals tend to avoid it, so it increases in numbers compared to other plants in grazed areas.
