Related species: Portulaca oleracea, common Purslane, is a sprawling plant with smooth, thick, fleshy, reddish stems. It produces single flowers sparsely although hybrid ornamental purslanes are floriferous. It is native throughout the U.S. and a well-known weed that can become a pest in gardens during hot weather but is easily pulled out. At one time it was valued as a salad plant because it has an exceptionally high iron content. There are a number of striking ornamental cultivars of Portulaca oleracea.
Cultivars: Sundial and Sundance series tend to stay open on cloudy days as well as in sunshine. Many other Portulaca cultivars are available.
