Portulaca oleracea 'Balriorg', also known as Portulaca oleracea 'Rio Orange', is one of the cultivars in the Rio Series. It is a prostrate, trailing, free-flowering annual that grows up to 6 inches (15 cm) tall and spreads up to 12 inches (30 cm) wide. The stems are clad with flat, fleshy, spatulate to ovate, succulent leaves. They are medium green and up to 1.25 inches (3.1 cm) long. The flowers are orange, with five overlapping petals and up to 2 inches (5 cm) in diameter. When grown as annuals, flowers bloom continuously from spring to first fall frost. When grown in a greenhouse type environment, flowers will bloom year-round. Flowers usually do not open on cloudy or rainy days.


It is grown as an annual plant, so it has no USDA hardiness zone.

How to Grow and Care

Portulacas tolerate many kinds of soil but prefer sandy, well-drained soil and love the full sunlight. These plants are excellent for high heat and drought tolerance and will seed and spread themselves very well. Some control methods may be needed to keep Portulacas from becoming invasive to areas where they are not wanted. These beautiful plants do spread quickly and very well.

These succulents require no attention at all when growing and flowering. However, you should remove them from the garden before Portulacas 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 cylindrical foliage of the plants retains moisture very well. Thus, regular watering is not required. When they are watered, just a light watering will do, as their root zone is very shallow.

The seeds of Portulacas should be sown on the soil surface following the last frost of spring. Ideally, these plants should be grown in a sunny part of the garden. If starting Portulaca indoors, then start about one and a half months in advance.
