- Description
-
Blue Star Creeper is an evergreen, herbaceous perennial, spreading ground cover with small, light blue flowers that blossom in spring. The plant is a native of Australia with a low-growing habit, often creating a mat as it forms roots and spreads. Although it throws off runners, it can be contained with a deep landscaping edging material. It flowers in early spring into summer and produces a carpet of white-blue five-petalled star-shaped flowers, making it a colorful groundcover.
Blue Star Creeper prefers partial shade or dappled sunlight; moist soil; and tolerates foot traffic. Because it is shade tolerant, it is a good ground cover for growing under taller plants. It is often found growing in moist sand or mud along the margins of creeks and streams, or among granite outcrops and wet depressions. This evergreen plant is easily ripped apart into small pieces, which make new plantings for early spring.
