- Stems are red colored growing from a weak central root. Leaves are rounded, deeply lobed with a waxy appearance that makes dense infestations easy to recognize.
- Flowers are pink with 5 petals and grow interspersed with the leaves; rather then above them.
- The seeds are small and rapidly transported to un-infested areas on boots, vehicles, and by wildlife.
