The three-leaf anemone ( Anemone trifolia ) is a plant from the buttercup family (Ranunculaceae).

features

The species is a perennial herbaceous plant , a Geophyt with a whitish "rootstock" ( rhizome ). It reaches a height of 10 to 30 centimeters. In contrast to the more widespread bush anemone , the sections of the stem leaves in the three-leaf anemone are not divided, but are regularly sawn. The three-piece stem leaves are whorled together (as with all wood anemone ( Anemone ), because this is a common feature of the genus). The remaining leaves are basal. Usually only one flower is formed on each stem. Each flower usually has six tepals . In each flower there are many stamens , the anthers are (bluish) white. Flowering time is April and June.

The number of chromosomes is 2n = 32.
