A well-planned garden will have plants and flowers that bloom and provide color throughout the spring, summer and fall. Keep your landscape looking colorful and cheery by adding some late-blooming flowers into the mix. By pairing these summer and fall bloomers with early blooming flowers, such as crocuses and hyacinths, your garden will have a continual array of blooms throughout the growing season.
Black-eyed Susan (Rudbeckia hirta), an annual, typically reaches a height of 1 to 3 feet and sports a deep yellow bloom and dark brown to black center. It blooms in June and can continue to flower until October. It prefers well-drained soils, such as a sandy loam, and will thrive in both sun or shade. It's considered a drought-resistant flower, making it a good match for areas with little rainfall. It should be noted, though, that its hardiness makes it an aggressive plant; it can take over an area if not provided with competition. It is recommended to plant these flowers along with another aggressive plant to keep them in check.
Canada goldenrod (Solidago canadensis), a perennial, is the perfect choice for nature lovers, as it attracts birds, bees and butterflies. It makes a good addition to meadow-type gardens and will grow in any type of soil, as long as it receives partial sun. Though it is often mistaken for the cause of hay fever, the culprit is usually ragweed, a similar-looking plant that blooms at the same time. The Canada goldenrod blooms during the late summer, producing a golden-yellow flower, and can continue to flower until October or November. It typically reaches a height of 3 to 6 feet.
New England Aster
The perennial New England aster (Symphyotrichum novae-angliae) typically blooms in August and reaches the end of its cycle come October. It is a tall plant, reaching heights of 6 feet, and produces lavender, blue or white flowers. It thrives in moist soils, with partial shade, and is a favorite of those with butterfly gardens because it attracts the Monarch butterfly. The New England aster blooms best when the roots are divided every few years, but do be aware that this is considered an aggressive flower. Plant it along with another aggressive flower, such as the black-eyed Susan, to give it competition.
