Overwintering Fall Bloomers: Is It Worth It?

The truth is, it depends. Most of us love to buy armloads of nursery-grown mums and asters each fall to decorate our drives, porches and patios. Then it gets cold, and we’re stuck with what to do with them before winter sets in. It seems wasteful to throw them all out. So inevitably, we tuck a few into the ground and hope for the best.

Sometimes we get lucky and they show up (finally!) in late spring…but more often not. So what gives?

In this article I’ll weigh the pros and cons of overwintering late bloomers. Some thrive in the garden and others don’t. In fact, many are bred just to get tossed. The trick is knowing which is which, along with a few tips that should significantly increase your chances for success.

Rose of Sharon to Brighten Late Summer

Who’s not familiar with rose of Sharon? A staple in older gardens and rural farmsteads, does it still have a place in today’s modern spaces? Yes! Fortunately, thanks to a number of improvements, there’s more to choose from than ever, including dwarf varieties and better flowers.

Rose of Sharon (Hibiscus syriacus or Althaea syriacus) has been gracing American yards and farmsteads for generations. Its very staying power over the years says it all for ease of cultivation, excellent longevity and valued late season color.

Black-Eyed Susans Ignite Summer Days

Indian Summer is big, bold and brassy

Who doesn’t adore black-eyed susans (Rudbeckia spp.) for their non-stop flowering and strong constitutions? Most cultivars sport bright shades of yellow and gold but tender varieties come in coral, rust, bicolors and even red. If you’re looking for long-lasting summer color to cheer you up, rudbeckia will do the trick.

Black-eyed (and brown-eyed, and green-eyed) susans are also commonly called coneflowers, a name that can refer to echinacea as well. To avoid confusion I’ll just call it rudbeckia here.
