What flowers are in season in Michigan during summer?
The Short Answer
Michigan summer offers the widest variety of local flowers all year, including sunflowers, dahlias, zinnias, lisianthus, hydrangeas, and garden roses from June through September. Warm weather and long days mean abundant, affordable, locally grown blooms. This is the ideal season for farm-fresh, seasonal arrangements.

Summer's abundance
Summer is the most generous season for Michigan flowers. From late June through September, local farms and gardens overflow with sunflowers, zinnias, cosmos, dahlias, snapdragons, lisianthus, and gladiolus. Hydrangeas hit their stride, and garden roses bloom in wave after wave. This abundance means arrangements can be full, varied, and richly textured while still relying largely on flowers grown close to home. It is also the season when a mixed local bouquet costs the least relative to its size, because supply is high and transport is minimal.
The dahlia and sunflower months
Late summer, roughly August into September, belongs to the dahlia. Michigan growers cultivate dahlias in an astonishing range of colors and sizes, from tiny pompons to dinner plate blooms as wide as your hand. Sunflowers dominate the same stretch, bringing bold cheer to any arrangement. Zinnias keep producing all summer, and their jewel tones make them a farmers market favorite. These are the flowers that define a Michigan summer, and our designers love this window because it allows the most creative, seasonal, and locally rooted designs of the whole year.
Caring for summer flowers in the heat
Summer heat is the main challenge for keeping cut flowers fresh. Blooms cut in hot weather need immediate hydration and a cool spot away from direct sun and warm windows. Change the water every day or two, since bacteria grow faster in warmth, and recut stems to keep them drinking. If you are transporting flowers to a summer event, keep them cool and out of a hot car for as long as possible. With a little care, summer blooms reward you with unbeatable variety and color that no other season can match.
Planning Tips From Our Designers
- Take advantage of peak variety and value with a mixed local summer bouquet.
- Choose dahlias and sunflowers in August and September for the best local selection.
