Pilea pumila aka Canada Clearweed

Taxonomy ID: 1393

Pilea pumila, commonly known as clearweed, Canadian clearweed, coolwort or richweed, is an herbaceous plant in the nettle family (Urticaceae). It is native to regions worldwide, with fossils of Pilea species being found dating back over 5 million years ago! Pilea pumila has an erect annual growth habit and may reach from 0.7 to 70 cm tall, with translucent and bright green foliage, turning yellow in autumn, opposite, simple with dentate margins, wrinkly (with depressed veins) and ovate, borne on long petioles. Small, greenish yellow flowers are borne in axillary cymes, unisexual with both genders occurring on the same plant, pollinated by wind and blooming from midsummer through early autumn, while the fruits (achenes) are green with purple markings. Pilea plants often have succulent, water-storing leaves and this particular species has a high tolerance for disturbance, making it common in and around buildings, in gardens and natural areas including forests, roadside or shaded conditions, rich and loamy soil, as well as in ecologically degraded areas. Pilea plants are known for the unique way that their fruits are protected, resembling a 'felt cap'.
