Description
A short-lived perennial that reproduces both by seed and creeping roots. Stems are erect and grow to 1 m tall with some branching in the upper part. There may be one - many floral stems per plant. Leaves are broad and heart-shaped with a pointed tip and clasp the stem. They are arranged alternately and are crowded on the lower stem. Leaves decrease in size higher on stem. Flowers are bright yellow with a darker yellow spot on the lower lip and are borne on the upper branches of stems. They resemble snapdragon flowers and can be up to 3.5 cm long, including the spur extending from the base. Fruits composed of two oval capsules to 7 mm long contain numerous, tiny brown/black seeds.

Key Identifiers
  • Creeping roots
