Thank you for contacting Toronto Master Gardeners.

Our publication Perennials for Full Sun: A Toronto Master Gardeners Guide provides detailed instructions on growing perennials.

Our guide, Long Blooming Perennials: A Toronto Master Gardeners Guide includes a limited list of perennials that bloom at least four weeks, listed by flowering time.

Perennials typically do not flower all summer long, but some perennials do flower longer than others. The key to having flowers throughout the summer is to plant a variety of perennials so that your garden always has something is in bloom. So, when choosing perennials, check the plant tag which should show the flowering period.

Here are five popular picks for tall perennials for sunny locations in the Greater Toronto area:

  1. Black-eyed Susan, Rudbeckia hirta, mid-summer to late fall flowering
  2. Butterfly Weed, Asclepias tuberose, mid to late summer flowering
  3. Purple Cone flower, Echinacea purpurea, June to August flowering
  4. New England aster, Symphyotrichum novae-angliae, fall flowering
  5. Tall Bearded Iris, late May to late June flowering.

Within a particular plant species, flowering length can vary by cultivar, and new cultivars are released regularly. I suggest you visit your local garden center and inquire about what long flowering perennial species are available.
