What does drought tolerance in plants mean?

Drought tolerance in plants refers to the capacity of a plant to survive and maintain functionality despite limited water availability. This ability allows plants to endure periods of dry weather without suffering from severe stress that would threaten their survival. Drought-tolerant plants often have specific adaptations, such as deep root systems, thicker cuticles, or reduced leaf surface area, which help them retain moisture and minimize water loss.

The concept of drought tolerance is crucial in landscape management, particularly in regions prone to dry spells. By incorporating drought-tolerant species into a landscape, a gardener can create a sustainable and resilient environment that requires less irrigation and can withstand fluctuating water conditions. Understanding this trait contributes significantly to effective landscape planning and water conservation efforts.
