10 Native Full-Sun Plants That Thrive in the Heat

"We're living through one of the hottest summers on record—and so are our plants. Here are 10 full-sun plants and flowers that thrive in the heat."

We’re living through one of the hottest summers on record—and so are our plants. For those of us who love to garden, this weather has the potential to interfere with the health of the plants that comprise your personal landscape.

In terms of honoring footprints and local ecosystems, seeking out native plants for your garden is a must. Aside from thriving within your natural climate without immense amounts of maintenance, many common landscaping plants not only non-native, but invasive, which can lead to environmental harm.

Though non-native plants are often picked for their beauty, there are plenty of native flowering plants that can decorate your garden, bring you joy, and survive the rising temperature. Here, 10 full-sun plants and flowers found across North America that thrive in the summer heat.

10 Native Full-Sun Plants and Flowers

1. Sunflower

As the name suggests, these iconic flowers love to soak up the sun! In addition to their bright brand of beauty, sunflowers enjoy a very deep history in North America: Indigenous peoples were growing them as crops as far back as 4,500 years ago.

The plant has the added benefit of producing edible seeds that can be snacked on, used for oil, and more. Sunflowers are distinctive and beloved: the flower is one of the most versatile plants you’ll find on this list in terms of habitat and is found in all 50 states, as well as parts of Canada and Mexico. Who knows—your flowers may grow tall enough to provide some shade.

2. Prickly Pear Cactus

Although one look at those spines is enough to make anyone wince, there are many benefits to planting prickly pear cacti if you live in an environment which supports their growth. These full-sun plants will thrive in much of the southern and western United States.

The best part of this cactus is that you can enjoy the fruits of your labor—the prickly pears are edible (and lend to a mean margarita)! There are several types of prickly pear, all with their own distinct vibrant color and flavor. What’s not to love?

3. Wood Lily

Found throughout most of the United States and half of the Canadian provinces, wood lilies are a stunning species native to North America that grows in environments with half to full sun. Though they grow widely, a relatively dry environment is crucial to their survival.

Although these lilies are lovely, keep in mind that, according to the ASPCA, wood lilies are toxic for cats when ingested. So plant with caution if you own some furry friends (or have some four-legged neighbors).

4. Carolina Rose
