Recently, you probably flipped another page on the calendar, marking the end of September and the beginning of October. If so, you're a more intrepid traveler of the seasons than I! October's thirty-one numbered days will have to wait a bit longer to form their five short lines across my kitchen wall. In the artificial world of the calendar, at least, I stubbornly cling to the last summer month. Perhaps I'll hold off on flipping that page for another few days, until Columbus Day (U.S.), famed for its fall foliage, forces me to recognize autumn's triumph. But don't let my summer procrastinating keep you from enjoying the autumn! Marie Iannotti, About's Gardening Guide, helps you celebrate the harvest season with some ideas for colorful fall shrubbery.
