Florist's Guide to Late Summer & Early Autumn Flowers
As summer's vibrant energy begins to mellow into autumn's rich tapestry, nature offers us some of its most spectacular floral displays. This transitional period, typically spanning late August through October, presents unique opportunities for florists to work with blooms that capture both the warmth of summer and the sophisticated palette of fall.
The flowers of this season tend to showcase deeper, more complex colors—burgundies, burnt oranges, golden yellows, and rich purples—while maintaining the fullness and vitality that summer brings. Understanding these seasonal varieties will help you create arrangements that feel perfectly timed and emotionally resonant.
Classic Autumn Blooms
Chrysanthemums (Mums)
Peak Season: September - November
Colors: Yellow, orange, burgundy, bronze, white, purple
Varieties: Button mums, spider mums, football mums, decorative mums
Chrysanthemums are the quintessential autumn flower, offering incredible diversity in form and color. Their dense, layered petals create rich texture in arrangements. Choose button mums for delicate, clustered looks, or dramatic spider mums for bold statement pieces. Football mums provide classic dome shapes perfect for traditional fall displays.
Care Tips: Cut stems at an angle under running water. Remove lower leaves and change water every 2-3 days.
Dahlias
Peak Season: August - October
Colors: Deep reds, oranges, yellows, purples, whites
Varieties: Dinner plate, pompon, cactus, decorative
Dahlias reach their peak just as summer wanes, offering some of the most spectacular blooms of the year. Their complex petal structures and bold colors make them perfect focal flowers for autumn arrangements. Dinner plate varieties can span 8-12 inches across, while pompon dahlias offer perfect spheres of tightly packed petals.
Care Tips: These flowers are particularly thirsty. Use floral foam or ensure stems reach water. Best when cut in early morning.
Asters

These delicate, star-shaped flowers bring a wildflower charm to autumn arrangements. Their small size makes them excellent for filling gaps and adding texture. They pair beautifully with larger statement flowers and bring a natural, informal quality to bouquets.

Transition Flowers (Late Summer Bloomers)
Sunflowers
Peak Season: August - September
Colors: Classic yellow, burgundy, orange, cream

Zinnias
Peak Season: July - October
Colors: Orange, red, yellow, pink, white, purple

Marigolds
Peak Season: June - October
Colors: Orange, yellow, red, burgundy
Varieties: African marigolds, French marigolds, signet marigolds
Often overlooked by florists, marigolds offer rich, velvety textures and intense colors perfect for autumn work. Their ruffled petals add volume and their warm colors complement the season beautifully. Use them as accent flowers or in mixed arrangements for rustic charm.

Late-Season Perennials
Sedum (Stonecrop)

Ornamental Grasses
