At Crystal Lake Garden Shop, we know that nothing brings a landscape to life like a continuous parade of blooms. Whether you’re dressing up porch containers or crafting a colorful perennial border, these “Summer Stars” are tried-and-true performers known for long-lasting, repeat, or non-stop blooms. Let’s spotlight the best of the best—our favorite annuals, perennials, and flowering shrubs for season-long color.
🌼 Annuals That Never Quit
Annuals are the go-to stars for reliable, non-stop bloom from planting day through frost. Here are a few of our favorites that thrive in the New England summer and deliver serious color payoff:
-
Supertunia® Petunias (Proven Winners) – These self-cleaning, vigorous bloomers create waves of vibrant color with minimal care. Perfect in hanging baskets or containers.
-
Sunpatiens® – Heat-tolerant and sun-loving, these hybrids fill in fast and keep blooming in beds or pots, even in full sun.
-
Calibrachoa (Million Bells) – These tiny petunia look-alikes bloom abundantly all summer with no deadheading required.
-
Zinnias – Butterflies love them, and so will you. Look for Profusion or Zahara series for compact plants with high bloom production.
-
Begonias – For shady spaces, Dragon Wing and Whopper varieties offer rich color and lush texture from June to fall.
🌿 Perennials That Keep Coming Back—and Keep Blooming
While most perennials bloom for just a few weeks, some go above and beyond with long bloom times or repeat flowering. These are perfect for creating a steady rhythm of color:
-
Coreopsis – Bright daisy-like flowers bloom for months, especially if you shear them back midseason.
-
Catmint (Nepeta) – Lavender-blue blooms and aromatic foliage keep bees and butterflies buzzing from late spring through summer.
-
Shasta Daisy (Leucanthemum ‘Becky’ or ‘Crazy Daisy’) – A summer classic that reblooms with deadheading and stands tall in any border.
-
Salvia nemorosa (‘May Night’, ‘Caradonna’) – Long-lasting purple spikes rebloom when trimmed after flowering.
-
Echinacea (Coneflower) – Modern varieties bloom longer and come in bold colors like orange, red, and coral in addition to classic purple.
🌸 Shrubs That Steal the Show
Flowering shrubs are the anchors of a landscape. These standout selections bring structure and color from early summer into fall:
-
Endless Summer® Hydrangeas – These rebloomers give you big mophead flowers multiple times through the season in blue, pink, or purple depending on your soil.
-
Rose of Sharon (Hibiscus syriacus) – A late-summer showstopper that bursts into bloom when others start to fade.
-
Knock Out® Roses – Blooming on and off from spring to frost with no fussy pruning or spraying—what’s not to love?
-
Butterfly Bush (Buddleia) – Fragrant, arching blooms bring pollinators in droves from midsummer on.
-
Spirea (‘Double Play’ series) – These compact, mounding shrubs offer spring foliage color and repeat pink blooms through summer.
🌞 Plant for Season-Long Impact
To design a garden that always has something in bloom, blend annuals, perennials, and shrubs with staggered or extended bloom times. Don’t forget to feed regularly—especially annuals—to keep the color going strong. And remember, many summer bloomers are also pollinator favorites, supporting bees, butterflies, and hummingbirds.
