Taxonomy

According to Meerow et al., cladistics suggests that the genus is native to the Americas. Several species have become naturalized (sometimes unintentionally) in other places like Hawaii, Indonesia, and Thailand. The species that are native to the higher altitudes in Mexico (e.g. Z. lindleyana, Central America (Costa Rica, e.g. Z. carinata) and parts of North America (e.g. Z. longifolia) or Argentina (e.g. Z. candida) represent the species having the greatest potential for cold hardiness.
