Moss rose plants are popular bedding plants sold in nurseries and home improvement stores in the spring. If you see any leftover annual plants on clearance in the summer, you might notice that the moss rose plants are usually just as lovely as they were in May, a testament to the plant’s toughness. The succulent leaves of the portulaca are another clue to the wonderful drought-tolerance of this low-growing annual flower. Many varieties have semi-double to fully double flowers that resemble miniature roses. Flowers come in hot colors, like yellow, orange, red, and bright pink. White, cream, and variegated flower colours are also available.

  • Portulacas need six to eight hours of full sun to reach their potential. If you try to grow portulacas in a shady area, they will pout and close up their flowers. You will also notice the flowers close at night and on cloudy days.
  • Portulacas demand a well-drained soil. If your your soil is mostly clay, you should grow your portulacas in containers rather than try to turn the clay into the sandy, rocky soil that these plants love.


  • Portulacas are drought-tolerant, but they aren’t cacti. The plants will tolerate periods of dryness, and you probably won’t return home to withered specimens after vacation, but flowering is better with regular irrigation. Drip irrigation is best, as sprinklers can disfigure the delicate blooms.

Temperature and Humidity

  • A native of Brazil, Uruguay, and Argentina, moss rose likes heat and can tolerate dry conditions. It is commonly used for xeriscaping.


  • Feed portulacas with a slow-release fertilizer (for flowers) twice a year, or once every 6 months.
