Plants that return every year are called perennials. (You can learn more in our article What’s the Difference Between Annual and Perennial Flowers.) So you’ll find flowers that come back every year described as “perennial flowers” in seed catalogs, online, or at the nursery. Here are a few of our very favorites so you can get an idea of the perennial flower options available for you to add to your garden.
BEARDED IRIS (IRIS GERMANICA)
Springtime blooms with shapes like frilly dresses open in a wide array of colors from these bulb flowers with lance-shaped leaves. Blooms are available in shades including blue, brown, peach, pink, purple, white, yellow, and lots of double-colored options.
Growing Zones: 3 through 10
Size: 12 inches to 40 inches tall by 1 foot to 2 feet wide

BEE BALM (MONARDA)
Also called bergamot, horsemint, and Oswego tea, bee balm is a great way to add some color and drama to the garden. Blossoms resemble fireworks atop tall blue-green stems and can be found in shades including pink, purple, red, and white.
