Designing Your Fall Flower Pot Arrangements
Switch out your seasonal decor when the temperatures drop. Annuals add vibrant color until frost, so combine them with some of best fall flowers for pots to keep the show going. Use plants with the same basic needs for water and sunlight; shade-lovers, for example, won't survive in full sun. Choose perennials recommended for your USDA Gardening Zone or, if your potted perennials overwinter outside, two zones higher.
Layering Plants for Depth and Interest
Fall containers aren't only about flower color, says Franklin Park Conservatory and Botanical Gardens Senior Horticulture Designer Barbara Arnold. Consider leaf and bark textures and shrubs with changing foliage, like oakleaf hydrangeas. "Think outside the box with perennials: Heucheras come in a range of colors, from lime green and burnt orange to deep, almost black tones. Hostas offer green, blue or variegated foliage that turns golden yellow in fall." Try cool-season annuals and vegetables like pansies, petunias, spinach and kale, and native grasses for movement, color and seedheads. Asters, mums, pansies, snapdragons, violas, goldenrods and rudbeckias are some of the best fall flowers for pots.

Choosing and Arranging Foliage and Fillers
Marie Genovese, with Gardener's Supply Company, says her company's experts recommend arranging fall plants for pots as "thrillers, fillers and spillers". Thrillers grow vertically, like cannas, while fillers have a horizontal habit, like petunias. Spillers cascade, like calibrachoas. "Generate energy and excitement with complimentary colors like purple and orange or yellow and blue," or use blues and pinks for soothing compositions. Greens, silvers and whites, she adds, look stunning.
Containers for Fall Flowers and Foliage
Choose durable containers, says Chuck Pavlich, Director of New Product Development at Terra Nova Nurseries. "Drainage holes are a must." He likes simple designs in smaller containers. "Crowded containers with too many elements look haphazard and poorly composed." Grow vertical plants in upright containers and heavy foliage and larger plants in wide, broad ones. He recommends using good potting soil and a slow release fertilizer supplemented by occasional liquid fertilizer.
