Portulaca, or moss rose, is an annual flower with a profusion of sunny flower colors combined with its toughness to make it a natural for difficult garden sites. It will do even better under less difficult conditions. Moss roses grow nearly prostrate - a mat of fleshy leaves with stems topped by flowers. Available in yellow, gold, orange, crimson, pink lavender, purple and white. Portulaca likes full sun, sandy soil and good drainage. Since they are frost-tender, they should not be planted outdoors until the danger of frost has passed.  Grows 4-8" tall, space 6-18" apart.

Reserve your problem areas for portulaca. They are notoriously good container plants that do not languish if you forget to water them one day.
