June is an exciting month in the garden when many beautiful perennials start bursting into bloom. With proper planning and plant selection, you can have nonstop color from alliums, irises and peonies earlier in June to hydrangeas, roses and daisies later in the month.
I love decorating my garden with June bloomers to welcome summer with their vibrant flowers. Here are 12 of my favorite perennials that shine in June:
1. Peony
Peonies usually bloom in June, and their big, romantic flowers open in early summer. The beautiful blooms come in shades of coral pink, white, red, and yellow. Tree peonies and intersectional Itoh peonies also come along and add their big, strange blooms to the show.
2. Iris
Bearded irises unfold their orchid-like blooms in June, featuring ruffled petals in a rainbow of colors like purple, blue, orange, pink, white, yellow and bi-colors They add vertical drama to garden beds and borders Siberian irises also bloom in June, showing off more understated blooms.
3. Allium
Alliums send up spherical flower clusters on tall, slender stems in May and June. The giant alliums can reach 4 feet tall! Popular varieties come in shades of purple, pink and white. Alliums make great cut flowers.
4. Salvia
The Salvia family features hundreds of species and varieties. In June, garden favorites like meadow sage (Salvia pratensis), Caradonna sage (S. nemorosa ‘Caradonna’) and pineapple sage (S. elegans) begin blooming. Their tapered spikes attract hummingbirds and butterflies.
5. Roses
June is prime time for rose blooming. This month, hybrid teas, floribundas, grandifloras, and English roses all bloom with beautiful, fragrant flowers. Prune spent blooms promptly to encourage re-blooming.
6. Lavender
When lavender spikes bloom in June, they are easy to spot. They look beautiful and fill the air with their sweet scent. English lavenders, such as “Hidcote” and “Munstead,” bloom first, and French lavenders soon after.
7. Tickseed
Tickseed (Coreopsis) blooms abundantly with its daisy-like flowers in June. It comes in colors like yellow, gold, mahogany and bi-colors with contrasting eyes. Deadheading spent blooms prolongs the floral display.
8. Delphinium
Delphinium are stars of the early summer garden with their stately spires densely covered in ruffled blooms. Colors include shades of blue, purple, pink, red and white. Remove faded flowers to encourage additional blooming.
9. Hydrangea
The blooming season for hydrangeas begins in June. This month, mountain, bigleaf, panicle, and smooth hydrangeas all have full flower heads in shades of white, pink, blue, and purple. Prune shortly after flowering concludes.

Garden phlox produces clusters of sweetly fragrant blooms starting in early summer. Popular varieties offer colors like pink, purple, red and white. Choose mildew-resistant cultivars for easy care.
11. Astilbe
With their feathery, fluffy plumes, astilbe blossom elegantly in the shade garden in June. They come in lovely pastel hues of pink, red, purple, peach and white. Their ferny foliage offers nice texture all season.
12. Yarrow
Yarrow bursts into bloom in June, showing off its umbrella-shaped flower clusters called corymbs. Varieties like ‘Paprika’ and ‘Summer Pastels’ bloom in vibrant shades of red, orange, yellow and salmon.
