Use the plant water needs as a guideline. Actual plant water needs will vary for several reasons, including weather conditions, soil type, sun exposure, root depth, wind and elevation. Adjust your watering schedule as needed to meet the plants' needs at your site. Water recent transplants more often than established plants.

Purple periwinkle is very similar to blue periwinkle, but has deep wine-colored flowers instead of blue.
It is a low-growing, spreading plant with glossy, dark green leaves. The long, ground-hugging stems will root as they spread, filling in bare soil. Peak bloom occurs in May. It may hold its leaves over the winter in an ideal planting site.
Purple periwinkle has been a long-lived, easy-to-grow groundcover at the Xeriscape Demonstration Garden. It grows best in partial shade. In full shade it rarely flowers. It is not well adapted to hot, dry, sunny areas.
No maintenance is required except removing it from unwanted spots.
