Biology

Common purslane reproduces by seeds, but it can also root from the stems or stem fragments which contact the soil. Common purslane is usually a prostrate plant from a taproot, with fleshy, reddish stems and succulent, green leaves. It can be mat-forming. Plants growing in shade are more upright and produce fewer leaves than plants in full sun. The leaves are oval, about 1/2-inch long, and alternate or nearly opposite, often in clusters. The leaf tips may be blunt or slightly rounded and petioles are absent. Tiny, five-petalled, yellow flowers may be seen in bright sunlight. Tiny black seeds are produced in small capsules that split open across the center. SPECIAL INFORMATION: The fleshy stems and thick, blunt leaves are distinguishing characteristics and also contribute to the plants’ survival after pulling. The stems are brittle and break easily, creating fragments which re-root easily after cultivation. Purslane has been used as a vegetable, but it may accumulate oxalates, which can be toxic.

Habitat

Common purslane is a common weed of gardens, lawns, waste areas, and cultivated fields. It grows best on rich, moist soils and can grow in sun or shade.
