The idea is to create a space or site that works with the existing conditions, or with minimal amendments, while also conserving water. 5. The different physical characteristics of xerophytes are described as being xeromorphic. Transpiration is natural and inevitable for plants; a significant amount of water is lost through this process. Light stress can be tolerated by dissipating excess energy as heat through the xanthophyll cycle. There are some which also present thorns. It is for this reason, many xerophytic plants share certain characteristics, especially in their leaves, stems and roots. Uncredited photos: Shutterstock. The spiny points of a cactus are technically the plant's leaves, although they certainly don't resemble a typical foliage. The color of a plant, or of the waxes or hair on its surface, may serve to reflect sunlight and reduce transpiration. Choose plants suited for your zone. If one area retains more moisture than another, such as a shady spot under the roofline or near an existing tree, this is a cue to avoid installing intolerant species there as theyll surely dislike being mired in soggy ground. Xerophytes have physiological and structural (xeromorphic) adaptations to maximise water conservation. Succulent plants are among the most resistant to long periods of drought and are usually also a source of food and water for other animals in the environment, including humans. a plant adapted for life and growth with a limited water supply See the full definition . These are covered by thorns both on the stem and on their leaves. During the day and especially during mid-day when the sun is at its peak, most stomata of xerophytes are close. Under conditions of water scarcity, the seeds of different xerophytic plants behave differently, which means that they have different rates of germination since water availability is a major limiting factor.
