Our friends at the Florida Wildflower Seed Co-op have produced a detailed report on Sunshine Mimosa, a native groundcover that is becoming very popular for Florida-friendly landscapes. This drought-tolerant, carefree creeping vine flowers all summer, has very attractive foliage, tolerates foot and light vehicular traffic, can stand alone or mix with grass or other groundcovers, and can tolerate periodic flooding. FANN sources for this plant can be found here.
