The Best Perennials for All-Summer Color

THE TED LARE LOOK

Our early spring blooming perennials are starting to wind down in Iowa, and we’re heading into summer. Flower gardens are looking fresh and full across the state, but as we head into the hottest months, some of those spring and early summer blooms are starting to fade a bit in the intensity of summer heat. 

There are actually quite a few different perennials that bloom beautifully for a long time and can withstand our hottest summer temperatures. Here are some of our favorite summer-blooming perennials to add long-lasting color to your garden.

Garden Phlox 

Phlox usually starts blooming in mid-July, and it keeps producing clumps of pretty flowers on tall stalks, overlapping with many fall-blooming perennials. Phlox does self-seed, so keep up with deadheading. Garden Phlox is available in a wide variety of colors like pink, red, purple, orange, and white.

Reblooming Daylily

Most daylilies only bloom for a couple of weeks each summer, but reblooming cultivars bloom multiple times in a season. There are two types; early/late bloomers and successive bloomers. Early/late bloomers usually flower in the spring and then again in the late summer or fall. Successive blooming daylilies produce batches of blooms, one shortly after another for several months. Reblooming varieties are available in a wide range of colors.

Shasta Daisy

Shasta daisy is an underrated summer blooming perennial. They’re usually white, making them versatile for pairing with other plants, and they’re a long-blooming, pollinator-friendly perennial. Daisies add a touch of classic simplicity to flower gardens. They bloom from July through the fall, with flower stems up to 3-4 feet tall.

Perennial Salvia

The Salvia family of plants includes both perennials and annuals. Salvia nemorosa, Salvia × sylvestris, and Salvia farinacea are perennial varieties. Salvia blooms for most of the summer, and if you keep up with deadheading you can extend their season even longer. 

Russian Sage

Russian Sage has a bit of a different look, with its many tiny purple flowers on thin spikes. While its foliage and flowers might be delicate and wispy, the plant manages to take up quite a bit of space. It can get as tall as 5′, and sprawl nearly as wide. 

Yarrow

Yarrow is a classic summer blooming perennial. It’s soft fern-like foliage sets off clusters of brightly colored flowers, from 1-3 feet tall. Yarrow is available in pinks, reds, yellows, and oranges. Yarrow does tend to naturalize and spread itself quite efficiently, making it ideal for pollinator gardens, xeriscaping, and re-wilding larger properties. 

 

coneflower, coreopis, allium ted lare

Coneflower

Coneflowers are another reliable all-summer bloomer, starting in June and going right through August, and beyond if the weather stays good. They do get quite tall, sometimes reaching heights of up 5 feet. Coneflowers are available in a wide variety of colors, including pink, purple, white, orange, yellow, red, and even green.

Coreopsis

Coreopsis produces small daisy-like flowers above fine, fern-like foliage. Heights vary a lot from one type to the next. Coreopsis bloom most of the summer, and when the flowers start to go off in late summer, you can encourage a second blooming by shearing back up to ⅓ of the whole plant. 

Allium

Alliums are truly a multi-season plant. While they don’t necessarily bloom all season long, their unique globe-like flowers turn into striking seedheads that provide beautiful visual interest all summer and stay standing in the winter. Most alliums come in shades of purple, but they’re also available in a wide variety of other colors. Different varieties feature varying shades of red, pink, white, and yellow. There are also early- and late-blooming varieties available.
