Some Like It Hot


Sedum rubrotinctum


Hesper aloe

When selecting plants for patios and balconies, consider those from habitats that most closely match your conditions, such as areas exposed to wind and sun, with limited water and soil, as well as large temperature fluctuations. Plants from areas like scrubland, screes, mountainsides, and deserts often make great patio plants.

A common thread among drought-tolerant plants is foliage that's hairy, waxy, hard, small, thin, and/or leathery. Deep taproots or extensive branching roots also help with drought resistance. Below are some examples of plants that can beat the heat!
