Fill your garden with color all summer long with plants that bloom this year and for many years to come.

Hardy hibiscus
A magnet for hummingbirds and butterflies, hardy hibiscus produces huge blossoms in vibrant shades of pink, red, or white and thrives in full sun. It typically has a longer dormancy than some other flowering perennials, but the reward of spectacular color will be well worth the wait.
Allium
Alliums thrive in locations with full sun, delivering colorful blossoms of yellow, white, pink, or purple. The whimsical structure, which can grow up to 3 feet tall, is made up of tall, thick stems and globe-like clusters of flowers. Alliums make great cut flowers, too, so you can fill the vases in your home with flowers from your own garden.
Becky Shasta daisy

Low-growing perennials that bloom all season
Ground cover perennials are a lovely way to upgrade the look of your front yard, flower beds, or garden pathways. You can find low maintenance, low-growing perennials that bloom all summer long, with these plants that also add color, minimize soil erosion, and prevent weeds. Here are a few of our favorites.
Lily of the valley
You’ll be hard-pressed to find a better low-growing perennial than Lily of the valley. It is considered one of the easiest to maintain among the perennial ground covers, and it grows best in partial shade with moist soil. If you can’t perfect these conditions, don’t worry. This lily is so hearty and adaptable that it can also do well in full sun or even full shade, depending on the moisture level of the soil. Not only are the snowy white bell-shaped blossoms beautiful to look at, but they are also some of the sweetest-smelling flowers out there.

This purple plant is an excellent ground cover for sunny or lightly shaded areas of the garden, filling empty spots in the yard and gaps between stepping stones. Creeping thyme also has the added benefit of choking out invasive weeds, so these blooms will keep your garden free from bothersome weed growth.

Sedum “Dragon’s Blood”
It should come as no surprise that Dragon’s Blood is known for the distinctive, vibrant red color of the petals. Sedums enjoy good sun and soil that isn’t too dry. They’re fairly undemanding though, so they can also grow in partial shade (but not full shade). Known to provide year-round beauty in your garden, you may still see the pretty rosette flowers peeking out from beneath the snow in winter.
