Quick Identification

  • Heat-shaped leaves are green and silver, hairy, and with round toothed edges

  • Stems are square

  • Flowers are light yellow, tubular, and grow in clusters

Competes with native plant species and provides poor forage and shelter to other local species. It is found in gardens, flowerbeds, and forests.

Mowing can spread the problem. Hand pulling is also not a guarantee as the plant can regrow from root and stem fragments even if composted. Effective pesticides are available. The best management method is prevention. Be careful of contaminated soil and transplants from infested sites.

Pale yellow flowers grow in clusters in the stems. They have one larger, upper lip, and a smaller bottom lip.

Leaves & Stems
Stems are square with alternating leaves. The leaves are heart-shaped, green with silver markings, hairy, and round-toothed. Plants originate from a central root base but creep along the ground as stalons take root.
