The flowers of fall are worth waiting all summer for. The flash of asters, the bright spark of goldenrods, and the velvety, Victorian richness of chrysanthemums push the garden to a crescendo of color even as the days grow shorter. Summer flowers fade as frost begins to nip the garden, but pansies, dianthus, and other cool-season flowers keep right on blooming while the trees above are putting on their spectacular autumn show.
While you're outside planting daffodils and tulips and other fall flowering plants for next spring, it's easy to slip in a few pansies, perhaps along a garden walk so you can enjoy their flowers as you come and go. In mild climates, pansies and charming little violas will bloom all winter and into spring. Calendulas, sometimes called pot marigolds, keep putting out their intense golden flowers through cool fall days, too.
Autumn Flowers Attract Butterflies
Planting fall flowers will bring your garden to life with butterflies. Coneflowers will be finishing their intense cycle of bloom, but goldfinches and chickadees perch on their handsome seed heads and help themselves. Especially at this season, migrating birds, as well as those that spend the winter in your garden, will take a keen interest in the seeds and berries your trees, shrubs, and flowers have produced during the long spring and summer.

Growing Fall Flowers in Flower Pots
Flower pots filled with cool-season blooms bring the palette of the season up close, to a porch or patio. "I love the idea of taking the plants and colors in the landscape and putting them in a pot, isolating them in a container. It's pretty cool," says Andrea Pellumbi, who works in the custom container department of a garden center in Portland. She likes to plant one large pot with strikingly variegated foliage plants or ornamental grasses, and stages smaller pots full of flowers around it. The plants in the big pot may hold up for a year or more, and you can change the color scheme in the smaller pots as often as you like. At this season, place a few pumpkins, gourds, or fancy ornamental squash among your flower pots: the abundance of the harvest will fill you with inspiration.
Colorful Glow of Autumn Flowers
Flower colors are more intense in the fall, and gardens are less demanding, which means that: plants will not need as much water as they did on hot summer days, and even weeds slow down as the days grow shorter and the temperature cools off. Cool-season annual and perennial flowers flourish in these conditions: they bloom vigorously, and their vibrantly colored flowers last a long time. Here are some of the best choices for flower beds or for pots:
Annuals:pansies, violas, petunias, snapdragons, callibrachoa, calendula. Perennials: Japanese anemone, perennial sunflowers (Helianthus), sedum, ornamental grasses, asters, chrysanthemums (also grown as annuals).
