There are two plants with the common name of Rose of Jericho: Selaginella lepidophylla and Anastatica hierochuntica. Both species dry out and appear dead without water, but revive once exposed to moisture. However, they are distinct species that are native to two different continents. Anastatica is a member of the Brassicaceae family and comes from the arid regions in the Middle East and the Sahara Desert. Selaginella is native to Mexico and parts of the United States and is a part of the spikemoss (Selaginellaceae) family. To counteract the confusion, Selaginella lepidophylla is sometimes called false Rose of Jericho and Anastatica hierochuntica called true Rose of Jericho.
