If you’ve got a garden soaked in sunshine, you need plants that can take the heat—literally.

But good news: there are plenty of full sun perennials that don’t just survive—they thrive—with little effort from you.
Whether you’re designing a new sunny border, filling in those hot, exposed patches, or refreshing a container garden on the patio, the low-maintenance perennials we’ve rounded up are colorful, reliable, and resilient. These blooms can handle drought, attract pollinators, and bring season-long interest, making them perfect for busy or beginner gardeners alike.
From Black-eyed Susans to showstopping Pink Muhly Grass, this list of tough, sun-loving perennials will brighten your landscape all summer long—and come back year after year with minimal fuss.

Bloom Time: Late spring to early fall
Height: 1′–3′
Spread: 1′–2′
Black-eyed Susans are an American classic—and for good reason. These cheerful yellow flowers with dark centers are more than just pretty faces. Once established, they’re impressively drought-tolerant, heat-resistant, and can handle the most intense afternoon sun without flinching.
Perfect for filling in borders or adding vibrant pops of color, Rudbeckia is a go-to for sunny beds. Deadheading spent blooms encourages more flowering, but even without the extra attention, they’ll keep on blooming. They thrive in well-drained soil and are a magnet for butterflies and bees, making them both beautiful and beneficial.

It prefers dry, well-drained soil and doesn’t like too much fuss—perfect for those hot, sunny spots where other plants struggle. And because it’s a late bloomer, it also serves as an important nectar source for bees and butterflies gearing up for winter.

Daffodils thrive in full sun and well-drained soil. And the best part? They multiply over time, creating larger and more dazzling displays every year. Not a fan of classic yellow? No worries—there are white, coral, and even double-flowered varieties to choose from.
