Plants to Grow in Late Summer
Many backyard gardens flourish in June and July, but start to fade as late summer approaches. If you are looking for plants that will thrive in the weeks of late summer, there are several annuals, perennials and vegetables that are late bloomers and can be enjoyed well into the fall.
Most annuals thrive in summer's heat and will keep blooming into early fall. Annuals can be planted right into your perennial garden to add fresh color and interest when your early blooming perennials are spent. Popular late summer blooming annuals include verbena, nicotiana, heliotrope, impatiens, begonias, geraniums and pansies. Annuals grown for their attractive foliage include dusty miller, coleus and caladium.
There are several perennials that bloom during the late summer. The colors of a late-summer perennial garden include the golden yellows of coreopsis, black-eyed Susan, Lemon Queen sunflower and yellow waxbells, as well as the violet-blue hues of purple coneflower, monkshood, New York aster, salvia, veronica, and Russian sage. Late summer is a good time to see where the blank spots are in your garden. Fill them with heat-loving perennials to extend the bloom time of your garden into early fall.
There are many vegetables you can grow in late summer that will give you fresh produce through the fall and into winter. Planting these hearty vegetables in late summer will yield a garden that can withstand the cooler temperatures of late summer and fall. Include any of the following vegetables in your late summer vegetable garden: onions, leeks, pumpkins, butternut and acorn squash, beets, radishes, parsnips, turnips, kale, radicchio, escarole, kohlrabi, cauliflower, broccoli, cabbage and Brussels sprouts.
Late Summer Flowering Plants
Summer-blooming annuals grow, flower and die back in one growing season. Remove fading flowers before seeds form to prevent self-seeding. The fragrant flowers appear 3 to 6 feet above the dark green strap-like leaves. Late summer flowering perennials commonly stay in bloom until cold winter weather occurs. Perennial toad lilies (Tricyrtis “Sinonome”) grow well in USDA zones 4 through 9 with 1-inch-wide purple and white spotted blossoms appearing on top of 2- to 3-foot tall stems during the late summer. Many different types of shrubs produce late summer flowers. Blush Satin rose of Sharon (Hibiscus syriacus “Mathilde”) grows as a deciduous shrub in USDA zones 5 through 8, reaching 8 to 12 feet tall and spreading 4 to 6 feet wide.
