Late-season blooms and upcoming sale

In Bees, Butterflies, Tonkadale Greenhouse by tonka_adminLeave a Comment

September signals the start of school, football, autumn decorating, and cooler temps (often very welcomed!). Despite summer winding down, it’s the perfect time to look around your gardens for the spaces that could benefit from new additions.

Consider adding late blooming perennials, too. Aside from adding color and extending the gardening season, later blooms provide a food source for pollinators, such as native bees who are storing food for spring and butterflies that are about to start their long journey south.

Of course, Minnesota hardy mums are a great option for color, fall décor, and pollinators. But there are many other wonderful late-season bloomers.

Being a late bloomer is a great thing! Here are some of the best:

  • Hardy mums – full sun.
  • Sedum by Tonkadale Greenhouse


    Sedum – full sun, dry conditions.

  • Hardy hibiscus – full sun, moderate watering.
  • Joe Pye weed – full to part sun, prefers moist soil.
  • Black-eyed Susans – full sun, drought tolerant.
  • Asters – full to part sun, moist well-drained soil.
  • Goldenrod – full sun, drought tolerant, does not cause allergies – it’s a garden myth!
  • Russian sage – part to full sun, drought tolerant.
  • Heliopsis – full sun, dry to medium soil.
  • Helenium – full sun, moderate watering.
  • Japanese anemone – part sun, prefers light soil and slight moisture.
  • Chelone – part sun, medium to wet soil.
  • Monkshood – part to full sun, moist soil. Be cautious – all parts of the plant are poisonous.

Try Witch Hazel for a late-blooming shrub. Not only does this unique plant offer autumn flowers, but it provides winter interest as well.

A great late-blooming vine is Sweet Autumn clematis, which really does live up to its name with wonderfully fragrant white flowers that slightly resemble jasmine in appearance.

Don’t forget about grasses! These are at their prime in the fall, adding stunning “blooms” to the garden while being the perfect companion for black-eyed Susans, mums and sedum, all while enhancing the fall-like look of the garden. Plus, the rounded, mounding grasses that cascade out from the center tend to allow for a little bare dirt hidden just beneath their blades, providing the perfect place for ground-nesting native bees that prefer bare soil to burrow into and call home.

Fall is a great time to plant perennials and perhaps the best time to plant trees and shrubs. With cooler temps the plants will experience less transplant stress than in mid-summer, and there is still plenty of time for roots to become established. Just be sure to mulch with a thick layer of straw or marsh hay after the ground freezes to protect plants from a freeze-thaw cycle (especially likely to happen if there is little snow cover).
