Wingpod Purslane

Portulaca umbraticola is a common weedy species of the southwestern United States, while in the southeastern United States it is usually restricted to sandy soils of granitic and sandstone outcrops. In 1982-1983, a new cultivar was introduced to the United States in hanging baskets, under the name Portulaca umbraticola ‘Wildfire Mixed,’ which appears to be selected from material from South America. There is no seed surface variability in any of the three subspecies.

Plants annual; roots fibrous. Stems prostrate to suberect; trichomes sparse at nodes and in inflorescence, stems otherwise glabrous; branches 5-20 cm. Leaf blades obovate, spatulate, or sometimes lan-ceolate, flattened, 10-35 × 2-15 mm, apex rounded to truncate; involucrelike leaves 4-5. Flowers 8-15 mm diam.; petals yellow or yellow tipped with red or copper, spatulate or obovate, 5-10 × 3-6 mm, apex acute or cuspidate; stamens 7-30; stigmas (3-)5-18. Capsules obovoid or turbinate, 3-5 mm diam., with encircling, expanded, membranaceous wing 0.5-1.5 mm wide proximal to suture. Seeds gray, round or elongate, flattened, 0.5-1 mm; surface cells stellate with long tubercles.

Portulaca umbraticola, also known as the wingpod purslane, is an annual or short-lived perennial succulent in the genus of flowering plants Portulaca.
