Blooming flowers often get associated with spring and summertime, but a great many beautiful blooms arise in September. Their colorful splendor and glory help to buffer the coming grey of winter. Let these fall blossoms inspire you and warm your heart while the farmers begin to harvest and winter winds wait on the horizon.
Pansies bloom every year in the fall. They flower in a wide array of vibrant colors, including purple, dark red, yellow, and white, as well as multi-colored combinations. Plant pansies in partial shade to full sun in your garden. If you pluck off the flowers as they start to wilt, your plant is more likely to produce flowers well into the fall months. Prune pansy plants after the first flush of flowers has died to encourage even more blooming as the weather gets cooler. (reference 1,2)
Roses stand out as one of the world's favorite flowers. Plant roses where they can get at least six hours of sun each day and prune them often and liberally to encourage blooming all through the summer and into September. Feed rose bushes after the first leaves begin to grow and feed them again after each series of blooms die off. Use mulch to discourage weeds and to help the soil stay loose and moist. (reference 3)
Calendula flowers blossom from summer through September. Calendula plants do best in sun to partial shade. Their blossoms come in red, gold and yellow hues. (reference 1, 4) Water calendula plants well to ensure that they continue to blossom through the fall. (reference 4)
Snapdragon blossoms come in yellow, crimson, pink and white. These fall blossoms will even withstand the first frost of the season. Snapdragons do well in full sun. Pull off dead and dying flowers to promote further blossoming into fall. (reference 1)
Marigolds come in yellow, orange, red, maroon, cream and various combinations of color. Plant marigolds after the danger of freezing temperatures has passed. Place them in your garden in a location where they will get plenty of sun and well drained soil and their blooms will delight you all autumn long. (reference 5)
Petunias come in well over a hundred different varieties and share the beauty of their blossoms from spring all the way until the first frost of fall. They come in a multitude of different colors and blossom sizes. Grandiflora petunias are the most common and have the largest blossoms. Multiflora petunias have smaller but much more prolific flower flushes. Milliflora petunias produce loads of tiny flowers an inch in diameter. Ground cover petunias will spread across a hillside to create a wall of blossoms. (resource 1)
