This document provides a list of plant species that thrive in the summer heat and can replace plants that struggle or die in hot weather. It includes perennials, annuals, herbs, grasses and vines that flourish when temperatures rise and humidity increases, such as Joe-Pye weed, butterfly weed, sunflowers, snapdragons, sedum, asters, lobelia, ornamental peppers, grasses and hyacinth bean vine. The list offers gardening options for areas where summer plants commonly "fizzle" due to hot, humid conditions.
