Identification

This is an erect, perennial forb that rises from ascending to horizontal rhizomes.

In early April it can be identified by the pointed, purple, three-lobed leaves laying flat on the ground. These are leaves that have overwintered from the previous year. The name hepatica is latin for liver, and refers to the shape and color of the leaves, which resemble the human liver.

After the flowers have bloomed 3 to 15 new leaves emerge from the base on slender, densely hairy, 2 to 8 long leaf stalks. The leaves are to 2¾ long, ¾ to 4 wide, and palmately divided into 3 lobes deeply cut to well below the middle of the blade. The base of the leaf is heart-shaped, broadly rounded and indented where the leaf attaches to the leaf stalk. The lobes are broadly oval to egg-shaped and pointed at the tip. The terminal lobe length is 70% to 90% of the total leaf length. The margins are untoothed. The upper surface is green, sometimes with purple mottles. The underside of the leaf is green or sometimes purple. When young both surfaces are densely hairy with long, soft, shaggy, unmatted hairs. As they age they become hairless or almost hairless.

By the time the flowers appear the overwintered leaves are dying back. The flowers are ½ to 1 wide and are born singly on densely hairy, leafless stalks. They have from 5 to 12 petal-like sepals (usually 6), 10 to 30 white stamens, and a green cluster of carpels at the center. The sepals are white, pink, or blue, egg-shaped or inversely egg-shaped. There are 3, sometimes 4, narrowly lance-shaped bracts with pointed tips subtending the flower.

Species

Round-lobed hepatica (Anemone americana) leaves are more shallowly divided into lobes with rounded tips. The terminal lobe length is 50% to 70% of the total leaf length. There are 3 broadly egg-shaped or elliptic bracts with rounded tips subtending the flower.
