Portulaca is a genus of the flowering plant in the family Portulacaceae comprising about 40 to 100 species found in the tropics and warm temperate regions. The members of the genus are commonly known as Purslane, Sun Plant, Rose Moss, and Wax Pink. Common Purslane (Portulaca oleracea) is widely considered an edible plant and, in some areas, an invasive type of weed. Purslane can be eaten raw or cooked and lends itself to stir fry dishes.
Portulacas are relatively hardy or half-hardy easy-to-grow annuals that reach 6 to 18 inches (15 to 45 cm). They have fleshy leaves, bloom from summer to the second half of fall, and have cup-shaped flowers, which can be yellow, red, pink, or white.
Growing Conditions
Light: Full sunlight
Water: During the growing period, these plants need frequent watering but let the soil dry between watering. Portulacas do not like wet conditions and will rot in constantly wet soil.
Soil: They prefer sandy, well-drained soil.
Fertilizer: An application of a balanced slow-release fertilizer with minor elements every six months.
General Care
Portulacas love full sun and tolerate many kinds of soil but prefer sandy, well-drained soil. These plants have high heat and drought tolerance. They spread easily, and some control methods may be needed to keep them from becoming invasive to areas where they are not wanted. Species such as Portulaca oleracea require no attention at all when growing and flowering. However, you should remove them from the garden before they have a chance to set seed as they may take over the garden. You do not need to water often for proper Portulaca care.
The seeds of Portulacas should be sown on the soil surface following the last frost of spring. Ideally, Portulacas should be grown in a sunny part of the garden.
If starting Purslane indoors, start about one and a half months in advance. It typically takes about one to three weeks for seeds to germinate at 70 to 86 °F (21 to 30 °C). Once ready, transfer the seedlings into the garden from 6 to 24 inches (15 to 60 cm) apart (depending on the size of the species). This should be done towards the end of spring.
