Plant from a dry climate capable of conserving water for longer that other plants, due to structural adaptations like dense pubescence, thick epidermis and resin cover which delay transpiration. Certain mangrove plants are also xerophytes, because water absorption is hindered by excess of salt.
Cultivar: Plant developed by cultivation and baptized by the gardener. The names of cultivars appear within quotes, to distinguish them from scientific names. (Also see Variety)
