Pilea pumila (L.) A. Gray
Canadian Clearweed, Clearweed
Urticaceae (Nettle Family)
USDA Symbol: PIPU2
A small, translucent-stemmed annual with short, curved clusters of inconspicuous, greenish-white flowers in the leaf axils. Plant lacks stinging hairs.
The distinctive clear stem, soft and with a watery look, is responsible for the common name. It is restricted to shady areas, where it may form a continuous cover over moist soil. P. fontana, very similar but with dull black seeds, occurs from western New York south to Florida, west to Nebraska and North Dakota.
