This biennial or short-lived perennial species blooms in the spring through early summer. Grows upright, to about 2ft.
Hairless leaves have different shapes at different positions along the stem. Basal leaves are mostly kidney shaped, while upper leaves are often lobed to egg-shaped. Leaves can vary in size but are often approximately 2-3in wide and have toothed, notched, or scalloped margins. Petioles reach 5in.
This plant can be highly variable in appearance, but is chiefly distinguished from other buttercups by its lack of hair, kidney-shaped lower leaves, and fruit shape.
