6 kinds of perennials that bloom all summer for a gorgeous garden

If you want your flower beds and garden to bloom for longer than a few weeks, you need to do your homework. In fact, many perennial plants, those that you do not need to replant every year, have relatively short flowering seasons, leaving your garden looking a little bare for a good portion of the summer. 

We’ve pulled together a list of perennials that will boast beautiful blossoms throughout the summer and return year after year with an abundance of color and fragrance. For a more interesting-looking flower bed, be sure to incorporate a variety of heights, a cohesive color scheme, and flowering plants that thrive in varying amounts of sunlight.

Check out these recommendations below to build long-lasting floral arrangements you can enjoy for months on end.

Perennials by height

Tall Perennials

Taller perennial plants prevent your garden from looking too uniform and crowded. A few of our favorites include:

  • Blue lupine
    With their intense blue color and tall, conical flowers, blue lupine will add color to your garden all summer long. Just sow the seeds in small pots this summer, then plant them in your garden next year to enjoy long-lasting blossoms for years to come.
  • Yellow hollyhocks
    Growing up to 48” high, yellow hollyhocks add months of sunny, golden hues to your yard.
  • Stella de Ora daylily
    As the name suggests, the blooms on this perennial last just one day. Don’t fret — a new one will replace it the very next day, guaranteeing a whole season worth of color and beauty. 

Short Perennials

Not a lot of space in your garden? Enjoy the beauty of flowering perennials with these smaller-scale plants that still deliver an abundance of brilliant hues. 

  • Dianthus
    With gorgeous blooms in shades of white, red, and pink, this alpine plant is super easy to grow from seeds and is drought tolerant, making it great for arid climates.
  • Shasta Daisy
    The Shasta daisy is very low maintenance and easy to grow, so amateur gardeners can plant and care for these blossoms without breaking a sweat. Plus, the pretty white flowers will bloom from mid-spring all the way through October!

Ground Cover Perennials

Ground cover perennials add color, minimize soil erosion, and prevent weeds, making them ideal to adorn your garden, walkway, or flower border. Incorporating these plants into your garden can also fill any sparse or bare areas. 

  • Lily of the valley
    You’ll be hard-pressed to find a better low-growing perennial than Lily of the valley. The snowy white bell-shaped blossoms are obviously beautiful to look at, and they’re some of the sweetest smelling flowers as well.
  • Sedum ‘Dragon’s Blood’
    With its vibrant red color, this plant offers year-round beauty in your garden, with pretty rosette flowers that can even peek out from beneath the winter snow. 

Perennials by sun requirements

Adding variety to your garden ensures that one too-shady or too-sunny season doesn’t destroy your whole arrangement. Additionally, knowing what circumstances your flowers thrive under will help you with planning so you don’t accidentally place sun-loving plants in a shady corner of the yard.

Full Sun

A certain amount of sun is a key component for any healthy plant, but some perennial plants do best when they are baked in sunlight all day long.

  • Geraniums
    Geraniums bloom brilliantly from June through October and come in an array of colors. Further, many species are both deer and rabbit resistant, so you won’t need to worry about pest damage. 
  • Coreopsis
    Great as a border accent, the bright colors of this daisy-like, sun-loving plant will attract beneficial bees and butterflies to your garden during the summertime. 

Partial Sun

Some perennials thrive with both sun and shade, so if your garden that can deliver both, add partial shade plantings for an all-season color show!

Summer Crush Hydrangea

With its shrub-like appearance, this flowering perennial will sprout bright pink blooms year-round.

Full Shade

If you prefer spending your summer days lounging in the shade, check out these long-blooming perennials that feel the same way.

  • Hostas
    One of the most popular shade-loving perennials, hostas have towering lilac petals shaped in small bulbs that add a little variety to the shape of your garden’s foliage.
  • Bugleweed
    These deep blue flowers are sure to brighten up even the shadiest parts of your garden. We recommend planting them against dark green foliage to really make the blooms pop. 

With a bit of planning, you can create a beautiful garden that will deliver color, dimension, and fragrance from early summer to the beginning of fall. And, like summer itself, your perennial garden will return each year, without you having to lift a finger.
