This genus of over 700 evergreen, moss-like perennials are grown for their attractive leaves and are naturally found in a range of habitats from semi-desert to tropical regions, with a few from alpine and temperate zones. Common names for different species include Spikemoss and Lesser Clubmoss. Plants in this genus are primitive vascular plants which produce two types of spore and have scale-like leaves with membranes on inner leaf sheaths where they join leaf blades - called ligules. Forms vary from small mossy tufts to vigorous scramblers with long, branching, bleached stems that can root. Selaginella moellendorffii is of scientific importance and is used as a model organism for the study of comparative genetics. For gardening purposes, use Selaginella for hanging baskets or ground cover - or keep under glass/as houseplants in cooler areas. Note that some species prefer slightly acid soil, others prefer slightly alkaline.
