Genus of about 700 species of evergreen, rhizomatous perennials found in a range of habitats, from semi-desert to rainforest, mostly in tropical regions, with some species in temperate and alpine zones. Selaginella, or Creeping Moss, was a Victorian favorite. These tender, spreading perennials are grown for their pretty, scale-like foliage. They can be used for edging greenhouse benches, covering pillars, planting in hanging baskets and decorating terrariums. Most of these plants are found wild in tropical America and Asia, but some come from China, Japan, North America, South Africa and Australia. S. martensii is a pretty plant that grows up to 9 inches high and wide. Its tiny, glossy green leaves are produced in thick, multi-branched sprays. S. kraussiana (Spreading Club Moss/Trailing Spike Moss) is a trailing plant that grows 1/2-inch high and has a limitless spread. Its tiny, bright green leaves overlap along jointed stems. This plant has a moss-like appearance. S. lepidophylla (Resurrection Plant) is a native of desert and semi-desert regions from Texas to South America. It is given its common name because of its habit of curling into a tight ball and turning brown when dry and opening out flat and turning green when water is again available.
