Fall Flowers in Ontario: What's in Season

The warmest, richest months of the Ontario flower year.

Fall wildflower arrangement with seasonal Ontario stems by Golden Hour Blooms Co., Markham florist

The short answer

Ontario's fall flower season runs from September into early November, until hard frost. The stars are dahlias, chrysanthemums, celosia, zinnias, sunflowers, and golden grasses, in warm tones of amber, rust, and burgundy.

Golden Hour Blooms Co., a wildflower florist in Markham, builds fall bouquets from these seasonal stems, from $50.

The Ontario fall flower calendar

MonthWhat's blooming
SeptemberDahlias at their peak, zinnias, sunflowers, cosmos, celosia
OctoberDahlias until frost, chrysanthemums, amaranth, grasses, rose hips
NovemberChrysanthemums, dried grasses and seed heads, greenhouse stems

Exact timing depends on the weather each year. The first hard frost usually ends the field dahlia season. See the full year.

The stars of fall

  • Dahlias. Huge, layered blooms in every colour. Enjoy them while they last; they're a short-season treat.
  • Chrysanthemums. Far more than the grocery-store pot. Spider and spoon varieties are stunning, and they last up to two weeks.
  • Celosia. Velvety plumes and crests that add rich texture.
  • Grasses and seed heads. The golden, gathered feel of a fall field.

"Fall is when the meadow turns gold. It's our favourite season to make bouquets."

Why fall bouquets last

Cooler weather is kinder to cut flowers, and stems like chrysanthemums and grasses are naturally long-lasting. Follow our care tips and a fall bouquet can look beautiful well into its second week.

Fall occasions

Fall bouquets are perfect for Thanksgiving, Diwali, autumn birthdays, and just-because days as the evenings get shorter.
