Clearweed

Clearweed, Pilea pumila, is a small, annual herb in the family Urticaceae native to moist, shaded habitats across eastern North America and eastern Asia, including the eastern United States, Canada, eastern China, Japan, and Korea. The species grows in dense colonies in wet woodland, stream banks, floodplain forests, and moist disturbed ground, often forming carpets on rich, moist mineral soils in deeply shaded forest understories. The common name refers to the translucent, watery stems and smooth, bright green leaves, which give the plant an almost glassy appearance. Like its relative stinging nettle, Clearweed is a member of the nettle family but lacks the stinging hairs, making it harmless to touch. The leaves are opposite, broadly ovate with toothed margins, and the plants bear inconspicuous tiny greenish flowers that are wind-pollinated, releasing pollen in small explosive bursts. Clearweed provides food for a variety of insects and invertebrates in moist forest understory communities. The species is not considered threatened and is common across its native range, thriving in the disturbed, humid conditions found along stream margins and in second-growth forest habitats. It is occasionally weedy in gardens and greenhouses.
