A xerophyte or xerophytic organism (xero meaning dry, phyte meaning plant) is a
plant, which is able to survive in an ecosystem with little available water or moisture, usually in environments where potential
evapotranspiration exceeds precipitation for all or part of the growing season. Plants like the
cactus and other succulents are typically found in deserts where low rainfall amounts are the norm, but xerophytes such as the
bromeliads can also be found in moist habitats such as tropical forests, exploiting niches where water supplies are limited or too intermittent for
mesophytic plants. Plants that live under arctic conditions may also have a need for xerophytic adaptations, as water is unavailable for uptake when the ground is frozen.
