Rose moss (Portulaca grandiflora) is a ground cover that grows to be about 4-8 inches tall and 2 feet wide. It has blooms that flower during the warm months, even all year in subtropical climates. Rose moss is easy to care for and needs little, if any, watering except in extreme drought conditions. Rose moss is annual plant; however, it does self seed and can grow back in subsequent years in warmer environments.
Choose a hot, dry location in full sun. Rose moss is often planted in garden beds with bulbs or in rock gardens.
Scatter and then rake rose moss seeds once the soil warms in the spring. Lightly water. The seeds should germinate within 2 weeks. As time goes by, you can pull unwanted plants if too many are thriving.
Dig a hole that is twice as wide as their current containers, but just as deep. Take the plants out of the containers and place them in the holes. Back-fill the soil and tightly pat it down to remove any voids in the soil. Water just enough to make the soil moist.
Space individual plants about 12 inches apart to make a nice ground cover in just a couple of months.
