Portulaca Species

Pink Purslane

• Pink purslane (Portulaca pilosa) is at its height in summertime, with 1-inch, narrow, fleshy leaves that trail along spreading stems and may form 8-inch mounds. This annual weed blooms in spring and fall, producing vivid pink flowers. Because of its fleshy, water-storing leaves, pink purslane grows well in dry or fast-draining soils that discourage other plants.

Little Hogweed

• Little hogweed or common purslane (Portulaca oleracea) is a wide-spread weed that grows in most climates, taking advantage of gardens from cold-winter regions to tropical islands. Purslane, however, contains many nutrients and is relatively high in protein, making it a valuable addition to salads or other dishes. Like pink purslane, it is a low-growing plant that may spread up to 2 feet wide, but produces thickened, oblong leaves and small yellow flowers.

Moss Rose

• Portulaca, or moss rose (Portulaca grandiflora) blooms from summer until the first frosts. It prefers warm weather and performs well with some supplemental water, and cultivars produce bright pink, red, orange, yellow or white single or double flowers. Use this annual along edgings, parking strips or in rock gardens, where the 6-inch tall mats provide a spreading, small-scale ground cover.
