Perennials Monthly Bloom Calendar | Petitti Garden Centers (2024)

Perennials are herbaceous plants that return year after year to deliver amazing color and long bloom cycles. Many are also excellent for pollinator gardening, and they look particularly striking when planted en masse! The tricky part is, different perennials do have different bloom times – and this can be confusing if you weren’t aware. No worries. If you love gardening with perennials, but you’re not quite sure what blooms when, scroll for a monthly sampling. It’s an easy way to curate a diverse, progressively flowering perennial garden for all-season color and attracting pollinators!

Early Spring Perennials (March & April): When the snow begins to melt and the soil begins to thaw, these spring beauties slowly emerge to brighten our gardens and our spirits. Combine any of these perennials with your favorite spring blooming bulbs for a long-awaited spring show…

• Sea Thrift (Armeria)
• English Daisy (Bellis)
• Leopard’s Bane (Doronicum)
• Candytuft (Iberis)
• Forget-Me-Not (Myosotis)
• Primrose (Primula)

If you’re looking for an early-blooming, long-lasting perennial for the shade garden, look no further than Lenten Roses. Also called Hellebores, these beauties are one of the first plants to bloom, typically in March, and their blooms last into June! They form low mounds of leathery, dark, evergreen foliage, so they also provide fantastic winter interest. They are excellent deer-resistant plants and they draw early-season pollinators to the shade garden.

May is when many of our best, most reliable perennials get started! Unlike our favorite spring ephemerals, these perennials enjoy the warm weather and remain for much of the summer.

From landscape staples like Catmint and Dianthus to uniquely-blooming beauties like Lupine and Baptisia, there are so many fantastic options to add color to the landscape in May.

The month of June is officially “Perennial Gardening Month” here in NE Ohio and it’s easy to see why! Many of our favorite long-blooming perennials show their beautiful faces this month and continually bloom throughout the growing season.

From Daisy family favorites like Blanket Flowers and Shasta Daisies to pollinator powerhouses like Daylilies and Lavender, there’s no shortage of bloom power throughout the month of June.

Things really start to heat up in the garden in the month of July and there are many perennials that thrive this time of year and continue blooming well into fall.

From summer-blooming staples like Coneflowers and Hardy Hibiscus to pollinator favorites like Milkweed and Bee Balm, there are so many fantastic perennials that brighten up the landscape in July and August.

The month of September is the time when most gardens lose much of their color. However, many perennial flowers provide the garden with color and rich texture during this month.

From flowering favorites like Black-Eyed Susan and Asters to fantastic foliage options like Ornamental grasses, there’s so much to love about the perennial garden in the month of September.

Knowing which perennials are the longest blooming in Northeast Ohio can help you plan and grow a lovely and progressively blooming garden across the seasons. Generally, bloom cycles will last longer or repeat more often if the perennials are grown in well-drained, nutrient-rich soil and if they’re deadheaded and fertilized regularly.

It’s easy to grow a perennial garden that’s always in bloom when you know what blooms when. March & April bring on a handful of perennials when we’re most eager to seesomething, anythingin bloom after a Northeast Ohio winter.
