Many gardeners know the struggle of those blazing, sun-baked spots where most plants just give up. If you’ve got areas that seem impossible, you’ll need tough varieties that don’t mind the heat or a bit of neglect.
The right plants for full sun and heat can turn your garden’s most difficult corners into lively, colorful spaces. Choosing species that come from hot climates, think flowering perennials, grasses, certain shrubs, and roses, makes all the difference! Knowing what thrives where the sun is relentless helps you build a low maintenance garden that still looks good even during the worst of summer.
Here’s a list of twenty tried-and-true options that don’t blink at full sun or high temps. Whether you want a low ground cover or a bold, flowering shrub, you’ll find something here for any garden design or landscaping challenge.
