Plants having thick fleshy tissue adapted to water storage are known as succulents. Some succulent plants store water in their leaves whereas those lacking leaves or having small leaves store water mainly in the stem. Deep root system adapted to the desert condition is their characteristic feature. Most of the cultivated succulent plants belong to more than 60 plant families including Aizoaceae, Cactaceae and Crassulaceae. Crassulaceae is the largest succulent family.
Unlike other plants, stomata of succulent plants are scotoactive i.e. they open at night and remain closed throughout the day. This prevents the excessive loss of water during hot summer days by transpiration. As carbon dioxide intake occurs at night, these plants have modified a form of CO2 fixation and photosynthesis called Crassulacean acid metabolism.
Large growing succulents form the foundation to the garden. As they are vigorous, they occupy large space in the garden and after they attain full size, it is very difficult to move them.
