Succulent

/ˈsʌkjələnt/

Definition

Succulent describes a plant or plant part with thick, fleshy tissues specialized for storing water. This characteristic occurs most often in leaves, stems, or roots and helps plants survive long dry periods. Unlike woody or thin-leaved plants, a succulent typically has enlarged water-storage cells and often a waxy skin that reduces water loss. The term refers to this water-storing growth form, not to a single plant family.

Botanical Significance

  • Water-storage adaptation: This trait helps plants survive long dry periods by storing moisture in leaves, stems, or roots, which reduces dependence on frequent rainfall.
  • Linked to drought physiology: Many plants with this feature also limit water loss through thick cuticles, reduced leaf surface, or CAM photosynthesis, a pathway that opens stomata mainly at night.
  • Useful for identification: In botany and horticulture, this growth form is a practical clue when recognizing plant groups adapted to arid or seasonally dry habitats.
  • Care implications: In cultivation, this trait usually points to a need for fast-draining soil and cautious watering, because water-storing tissues can be damaged by long periods of saturation.
