Leonurus sibiricus is a herbaceous annual or biennial with upright stems that grow from 20 to 80 cm tall. Plants have long petioled basal leaves, that are ovate-cordate in shape. The leaves have toothed margins and are incised with deeply cut lobes. Typically one or a few flowering stems are produced from short tap-roots. The lower stem leaves are deciduous and wither away as the plants begin blooming. The petioles of the leaves, midway up the stems are 2 cm long. The flowers are produced in many flowered verticillasters, produced in whorls around the top half or more of the stem. The flowers are sessile with 8 mm long calyxs that are tubular-campanulate in shape. The corolla is white or reddish to purple-red, with an upper lip that is oblong in shape and longer than the lower lip. When flowering is done, brown oblong shaped nutlets are produced in good number.[2] Blooming occurs from July into late September, but when climate permits, flowering can occur year round.[3][4]
This species habitat within its natural range, is stony or sandy grasslands or pine forests.[5]
