In late summer, early-spring flowers fade and wilt in the bright sun, but July and August blooming flowers arise to colour the garden and liven it up. These flowers thrive in the warm, dry and sometimes humid climate and appear in a variety of shapes, colours and sizes, each with its own distinctive growing needs and spread habits.
Petunias are a popular summer garden flower grown in containers, beds and borders that add colour from midsummer through to fall. Depending on the variety, these attractive annuals grow between 4 and 20 inches high. Grandiflora petunias produce larger flowers, some up to 5 inches wide, while multiflora petunias are easier to grow and produce 2- to 3-inch-wide blooms. Plant these sun-loving flowers in well-drained soils in a spot that receives full sun all day long.
With a moderate growth rate and long-lasting bloom period, the hedge coneflower, white coneflower (Echinacea purpurea "White Swan") or simply coneflower is a 1 ½ to 2-foot tall and 2 ½-foot wide perennial with daisy-like blooms that dresses up a garden during July and August. These butterfly attractants are moderately-drought resistant and tolerate poor soils, humidity and high heat, although they prefer a partially shady planting site. Each flower features a greenish-copper cone surrounded by 4-inch-long white petals. The white coneflower thrives in U.S. Department of Agriculture hardiness zones 4 through 9. Plant these flowers along a border, flower bed or container for beautiful colour through the hot summer.
"Becky" Shasta Daisy
Belonging to the genus Leucanthemum, this showy variety of the shasta daisy features large white flowers with yellow to golden-yellow centres supported by 3-foot-long sturdy stems. This long-lasting perennial flower blooms in mid-July and continues through fall. Becky shasta daisy also attracts butterflies and requires full sunlight and well-draining, moist soils in U.S. Department of Agriculture hardiness zones 5 though 8. It grows in clumps and enhances borders and beds.
These popular woodland flowering shrubs bloom from mid to late spring through July and August until early fall. Hydrangeas require little care or maintenance provided they are planted in moist, well-drained soil in partial shade. Oakleaf hydrangea (Hydrangea quercifolia) grows 4 to 6 feet tall and features 4- to 10-inch flowers that bloom from July to September, with varieties such as "Alice" and "Snow Queen." Smooth hydrangea (Hydrangea arborescens) is another fast-growing shrub with white flowers that blooms from the end of June through September.
