Water retaining plants adapted to arid climates and/or soil. Use this tag with questions about caring, propagating and identifying tomato succulents.

Succulents is a general term referring to -retaining plants adapted to arid climates and/or . They are not a genetic group as such, and should not be confused with cacti. Although cacti are succulents, there are many unrelated succulent genera.

Succulents store water in their , , and . Geophytes which store water in underground storage organs such as tubers, corms, and rhizomes; may be considered succulents.

Water saving adaptions found in succulents may include:

  • Crassulacean acid metabolism
  • Leaves that are absent, reduced, or cylindrical/spherical in shape (reduced surface area)
  • Reduced number of stomata
  • Photosynthesis mainly occurring in stems rather than leaves (eg. cacti)
  • Compact, reduced, columnar or spherical habit (reduced surface area)
  • Ribs enabling rapid increases in volume to contain water when available
  • Waxy, hairy, or spiny outer surface to create humid micro habitat
  • Roots near ground surface to absorb water from light showers or heavy dew
  • Ability to retain water despite high internal temperatures
  • Very impervious outer cuticle
  • Mucilaginous internal content (eg. aloe sap)

Succulents tend to come from dry areas of the tropics, and sub-tropics.

Use this tag for all general questions about succulents. These might include general care, or planning/caring for a xeriscape bed. Questions about specific plants should use the tag(s) for that plant, instead.
