Make heat tolerant perennials the main event in your summer flower garden and it will look fabulous year after year with very little input from you as they're so low maintenance. This is particularly important if your summers are hot and arid, you're looking for options that help you conserve water, or you simply like the idea of plants that aren't needy.
The plants that can cope with hot conditions usually originate from hot and dry areas such as Florida, Texas and California. So if this is your locality, match your perennials to the conditions in your backyard and they will thrive. Use local native plants that are adapted to deal with the heat already and you'll have a better success rate.
