Portulaca Gandiflora is often thought of as rock garden plants because they do so well in that setting. They are tender annuals with succulent, needle-shaped leaves and trailing stems 6 to 8 inches long. The flowers are bright and papery textured in shades of pink, red, yellow, salmon, orange purple, and white.
They are normally sold in a mixture, not as single colors. They open in sun but close at night and on cloudy days. Since they are gloriously drought-tolerant, you need to put them in pots, window boxes, or any container that I might forget to water from time to time.
If you want to grow Portulaca then transplanting is difficult it is best to start the seed directly in the garden when the soil is warm. A warm sunny exposure is essential as this is a site with well-drained soil. Thinning is not necessary. They will tolerate poor soil as well as hot, dry conditions. On top of all that, they will self-sow!.
