What type of plants does LEED promote for water-efficient landscaping?

LEED promotes the use of drought-resistant plants for water-efficient landscaping because these plants are specifically adapted to thrive in conditions with limited water availability. By selecting drought-resistant species, landscape designers can significantly reduce the need for irrigation, which is essential for conserving water resources. This aligns with LEED's overall goal of promoting sustainability and reducing the environmental impact of buildings and their landscaping.

Drought-resistant plants typically have features such as deep roots, thick leaves, and waxy surfaces that minimize water loss, allowing them to survive and flourish in arid conditions. This approach not only conserves water but also supports ecological health by promoting the use of native or well-adapted species that require minimal maintenance and have greater resilience to local climate conditions. In contrast, the other types of plants mentioned would generally require more water, thus not aligning with the objectives of water efficiency that LEED seeks to achieve.
