Heat and Drought Tolerant Annuals
Heat and drought tolerant annuals can be just as attractive as thirstier, more heat-sensitive annuals. If you have hot, dry conditions that doesn’t mean you can’t grow beautiful and colorful plants. Besides colorful blooms, many of these drought tolerant plants are protected by shimmery foliage that “glows” in the landscape - especially when contrasted with green-leaved plants. Annuals with this silvery, furry foliage actually have tiny, light-colored hairs on their leaves and stems that reflect heat to keep the plant cooler.

Succulents are another easy-to-recognize group of heat and drought resistant plants. They produce plump juicy-looking leaves that store water for long periods of time. Succulents are available in an array of foliage colors and forms. They’re incredibly versatile and will do well in containers, tucked between rocks, grown as a houseplant by a sunny window, or used as groundcover in difficult, dry locations.

Heat and drought tolerant annuals are low maintenance, making it easier on the gardener, the environment and the water bill, as they take less water and attention. They’re also great for planting in containers since they’ll survive those days when you accidentally forget to water. Just plant them in a potting mix or soil that drains easily, and allow it to dry between water applications . You can spend more time this summer just sitting back and enjoying the view from the shade of your patio umbrella!
