We immediately think of mums, but there are also ornamental kales and cabbages for sale. They are hardy even after frost and as temperatures drop, their colors often get deeper. Many garden centers have perennials, shrubs and trees on sale at this time so take advantage of lower prices and add more life to your garden.
And of course, autumn is the time to plant tulip and daffodil bulbs for color next spring. And remember the smaller bulbs like crocus, grape hyacinth and snowdrops which are the first to pop in early spring.
