You can start the seeds indoors eight weeks before your last frost date for earlier flowers, or plant them in the ground after last frost. The seeds take about two weeks to germinate in warm temperatures of 75 to 85 degrees F. Plants also self-seed generously, so learn to recognize young seedlings in the spring garden.
The low water requirement of the moss rose makes it a natural choice for the container garden. You can include it in containers that are exposed to winds, such as on a patio or dock. The trailing habit of the moss rose works well in hanging baskets. Portulaca behaves itself as a ground cover, never going out of bounds, so try it in a small garden or fairy garden.
#companionplanting Moss rose plants make good companions for flowers that also thrive in hot, dry, sunny gardens. Gomphrena flowers, zinnias, and dusty miller look handsome planted with a moss rose border.
