The succulent plants, commonly termed as fat plants or mere succulents can be defined in botany as the plants that have thick and fleshy body parts when compared to the other normal plants. These thickened parts help to store water, as usual, these types of plants are found in hot climates and poor soil conditions. The name “succulent” is derived from “sucus”, a Latin word, which means sap or juice. Generally, any part of these plants can be thick and fleshy like stems, leaves and sometimes roots. Succulents are commonly seen in the gardens as ornamental plants, obviously due to their unusual structure and distinct appearance. Types of Succulent Plants
Succulent plants are found in around 60 plant families. Most members of the families like Agavoideae, Cactaceae, Crassulaceae and Aizoaceae are succulents. Such plants are endemic to the areas having low rainfall and high temperature. They have the capability to survive on least water sources like dew and mist. The families having succulents are:

The succulent monocotyledons of the American continent have distributed into many important succulent families, which includes the Agavaceae that produces flower spikes and distinctive rosettes. The Agavaceae family includes Prochnyanthes, Agave, Hesperaloe, Polianthes, Beschorneria, Yucca, Manfreda and Furcraea.
This species of Agavacea family produces many offsets, but each reset has only a few narrow and long leaves in the blue-gray shade. These leaves grow about 3 feet long and have bud imprints on the surface. The spike of this plant has flowers with greenish-yellow shade. This plant is hardy to cold climates. Some of the other succulent species of this family are Agave Americana, Agave x Arizonica and Agave Atenuate.

Some species are endemic to the Pacific area and Australia. All species of this family are succulent plants, but includes a vast range of different succulent structures such as the pebble-like leaf to small shrubs having fleshy leaves.
This species of Aizoaceae family is endemic to the South African regions, where there is both winter and summer rainfall. These plants have light pink, large flowers with a stripe of darker shade found in between the petals. Some other examples, Aloinopsis Orpenii , Antimima Concinna and Aptenia Cordifolia.

Rosettes of this species are large and formed from the pale green leaves. The lower part of the rosettes have reddish prickles and white pustules. The edges of the leaves have several sharp and small reddish teeth. These plants are inhabited in the dry and hot mountainous areas of Zimbabwe. Some examples of this family are Aloe Affinis, Aloe Africana and Aloe Arborescens.
