Purslane (Portulaca)

Portulaca is a large genus of flowering plants with succulent leaves and bright, showy flowers. The [North Carolina Extension Gardener Plant Toolbox](https://plants.ces.ncsu.edu/plants/portulaca/) uses common names including purslane, moss rose, and rose moss, and notes that the genus includes many species with different root forms and growth habits. ## Appearance Portulaca species vary from low, spreading forms to plants with a more upright or shrubby habit. Leaves may be fleshy and narrow or broader, and flower colors differ among species and cultivars. Many flowers open in sunshine and close at night or on cloudy days. ## Growing Conditions Grow in full sun and in soil that drains well. North Carolina Extension describes Portulaca as heat- and humidity-tolerant and suited to dry or moderately moist soil. Individual species and named cultivars differ in mature size, hardiness, and flowering season, so use the species name when selecting a precise garden footprint. ## Maintenance In outdoor plantings, remove spent flowers if you want to limit self-seeding. Let the soil drain between waterings and avoid waterlogged containers. Because the genus includes annual and perennial species with different habits, care should follow the identified species or cultivar.
