The plant generally has a large basal rosette and smaller leaves further up the stem, each with 5–9 nearly round leaflets.^[2] Most prominently blooming in early spring and early autumn,^[2] the inflorescence is several centimeters long and bears many flowers with white petals just a few millimeters in length.

Toxicity
