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 water-retaining plants adapted to arid climates and/or soil. 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.
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.
