Top 8 Perennial Flowers to Plant in August
Crocosmia:The flowers resemble small lilies and are beautiful choices for flower arrangements. At 1.5 to 4 feet high with a 1-to-2-foot spread, crocosmia also makes an excellent ground cover.
Poppies:Depending on the species, poppies can flourish in hardiness zones 3 to 9, and grow from 12 inches to 4 feet in height.
Lupines:These admittedly short-lived perennial flowers bring showy, pea-like flowers in colors from white to red to blue and purple. Some varietals are bicolored.
Daylily:Daylilies are not related to “real” lilies, even though they look very much alike. They flourish in a wide range of hardiness zones, from 3 to 10.
Cornflowers:Cornflowers can be annuals or perennials, but one perennial type is Centaurea montana, or the mountain bluet. A member of the aster family, this unusual flower grows best in zones 3 to 8.
Foxgloves:This plant is famous for its clusters of 2 to 3 inch long, bell-shaped flowers that bloom on 2-to-5-foot spires. The eye-catching flowers come in colors of pink, white, yellow, or purple.
Rudbeckia:The plants grow from 18 inches to 7 feet tall with a 3-to-4-foot spread. Coneflowers have attractive, deeply cut foliage along with their beautiful flowers.
Salvias:Salvias are basically types of sage. Common sage is grown both as an herb and for its beautiful blue flowers, which appear in whorls on square stems in late spring.
