It’s easy to plant a garden that is colorful and interesting in June, more difficult is designing a garden that shines in October. Read Autumn Gardens by Ethne Clark (Soma, 1999) to learn both design principles and the best trees, shrubs, perennials, bulbs and grasses to plant in fall. Oakleaf hydrangea, Canadian serviceberry, species roses, and sedums are just a few of the plants featured that will extend the garden interest beyond Labor Day.
