Discussion
Subspecies 3 (2 in the flora).
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.
Selected References
None.
