Spikemosses, plants of the genus Selaginella, are commonly grouped in with traditional mosses and are sometimes called club mosses. In truth, they are very different plants. Spikemosses do prefer similar conditions, and do quite well in the humid confines of a vivarium. Spikemosses make great ground cover, and generally grow very well from clippings. In fact, Josh’s Frogs recommends dividing up any spikemosses before putting them in the vivarium, and planting them in different areas. Spikemosses can be tricky to grow in improper conditions, but grow quickly once established.
