7 Perennial Plants That Tolerate Summer Heat

Most perennials will stress and wither as the summer temperatures begin to heat up. Growing slows as the blooms start to lose their spark. Here are 7 perennial plants that will tolerate the summer heat and shine on to fall. 


Phenomenal Lavender


Introduced in 2012, the Phenomenal Lavender has great tolerance to heat and humidity. A strong and faster growing perennial, the Phenomenal will not only bloom continually throughout the summer, but is a worthy choice as a perennial for year round beauty. 


Pineapple Sage


One of the most wonderfully fragrant perennial herbs is the Pineapple Sage. Although this sage dies back to the ground over winter, the Pineapple scented flowers and leaves will delight your senses during the heat of summer. An added treat are the tall red spike flowers that attract hummingbirds and bees. Use the leaves and flowers in baking, spreads and drinks.


Black Eyed Susan Goldsturm


A strong bloomer from early to mid summer, then deadhead for another flush of beautiful yellow flowers that often last until first frost. Black Eyed Susans rudbeckia bloom continually through heat and humidity. 


Russian Sage 'Little Spire'


An underused perennial, the Russian Sage 'Little Spire' with just a small amount of space will shine over other plants in your garden. Russian Sage produces tall lavender blue fluffy plumes throughout mid to late summer. It pairs beautifully with the red spikes of the Pineapple Sage. 


Cheyenne Spirit Coneflower


Maintenance free and no deadheading required for this amazing echinacea. Great for naturalizing, coneflowers are drought tolerant. Attracts butterflies and bees. Let seed pods remain on the plants over winter to feed the birds. 


Yucca


The yucca color guard and bright edge yucca are evergreen perennial plants that are heat tolerant. These native perennial plants produce fragrant tall white flowering stalks over summer. 


Ornamental Grass


Plant these ornamental grasses among your summer flowering perennial plants for additional color and interest. Native grasses like the Prairie Dropseed, Schizachyrium scopartium 'The Blues', and Panicum Cloud Nine are tolerant of summer heat.
