Term (also xerophyte) for "drought-loving" plants that prefer extremely dry habitats or can adapt to deserts, steppes, rocks, saline landscapes or even winter-cold areas (frost drought or winter drought = state of water shortage). Such plants are called xerophytes (or xeromorphic plants) and include, for example, agaves, cacti, eucalyptus and certain conifers. A distinction is made between different types, which react in different ways to a lack of water or are formed accordingly. For example, through deep rooting down to the groundwater level, dry dormancy or through special osmotic absorbency of the roots. Some grape varieties have also adapted particularly well to dry environmental conditions. Although they are not xerophilic, they have developed a resistance to drought. See also under water balance.
