Will Coneflowers Survive The Winter In Pots?
Q: My wife and I planted coneflowers in pots to encircle our pool for a wedding. I have always planted perennials in the ground to ensure their winter protection. Can I expect coneflowers to survive over the winter in pots?
A: My bet is on the coneflowers. They’re tough and winter-hardy down to minus 30 degrees after dying back to the roots in the fall. Of course, the pots will be ugly then, so once you remove those brown stems, plant some annuals like ornamental cabbage, chard, and pansies to make spots of color around your pool.
