succulent (redirected from Succulent plant)

succulent (sŭk`yələnt), any fleshy plant that belongs to one of many diverse families, among them species of cactus, aloe, stonecrop, houseleek, agave, and yucca. Most succulents are indigenous to arid or semiarid regions, and their succulence is simply an evolutionary adaptation to the extreme heat and dryness of the environment. Typically the plants have greatly reduced leaves with a hard and heavily cutinized outer surface which minimizes evaporation from the inner, juicy tissue that can retain and store water over long periods. Many are grown horticulturally for their interesting and often grotesque forms, e.g., the ice plant; a few have very attractive flowers.

succulent

Any plant with fleshy, thick tissues adapted to water storage. Some succulents (e.g., the cactus) store water only in the stem and have no leaves or very small leaves; others (e.g., agaves) store water mainly in the leaves. Most have deep or broad root systems and are native to either deserts or regions that have a semiarid season. In succulents, the stomata (see stoma) close during the day and open at night—the opposite of the usual pattern—in order to minimize transpiration.
