Ten-petal anemone

Anemone berlandieri, commonly called ten-petal anemone or Berlandier's anemone, is a small spring-flowering perennial herb in the Ranunculaceae family, native to the south-central United States — chiefly Texas, Oklahoma and adjacent regions — and northern Mexico, where it grows in open prairies, glades, woodland edges and rocky calcareous soils. The plant arises each year from a small, tuberous rhizome that remains dormant during the hot summer months. It produces a basal cluster of long-petioled, three-parted, deeply divided leaves with toothed lobes that often appear after the flowers. A single, slender, hairy scape rises 10 to 30 centimetres above the ground, bearing a whorl of three deeply divided involucral bracts midway up the stem. A solitary terminal flower 2 to 4 centimetres across crowns the scape, with 10 to 20 narrow, petal-like sepals ranging from white through pale lavender to deep blue or pinkish, surrounding numerous yellow stamens and a conspicuously elongated, cylindrical head of greenish pistils that develops into a thimble-shaped fruiting head of woolly achenes.
