Geranium lucidum grows predominantly as an annual weed though it may become biennial depending on moisture conditions.
Foliage
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
Flowers are pink with 5 petals and grow interspersed with the leaves; rather then above them.
Fruit
The seeds are small and rapidly transported to un-infested areas on boots, vehicles, and by wildlife.
Ecological Threat
Geranium lucidum grows in the Pacific Northwest predominantly as an understory species intermixed with grasses, forbs and moss.
