The Best Perennials for Zone 7
Zone 7 is described as having an average minimum temperature of 0 to 10 degrees Fahrenheit. This zone includes cities such as Oklahoma City and Little Rock Arkansas. Perennials in this zone must endure a mild winter to come back the following spring. Perennial plants are a good choice for low maintenance and low cost landscaping. Since the plants return year after year with minimal special care, your garden can be full of blooming plants to enjoy.
Geranium 'Pink Spice' (Dwarf Cranesbill Geranium)
The 'Pink Spice' geranium has small scalloped leaves with pink flowers. The flowers bloom in summer and fall. This plant requires full sun and good drainage and makes a good edging plant. These plants also work well in a rock garden or in containers, where the flowers can cascade.
The astilbe is a perennial that tolerates shade well. The leaves are dark green and fern-like and the flowers are a fluffy upright plume in white, pink or red. These plants bloom from late spring to late summer. These plants require no special care other than frequent watering and spread to 48 inches. The flowers attract butterflies and can be used in dried arrangements.
The blanket flower (gallardia) produces a red daisy-like flower with a yellow border. These flowers like full sun and make good cut flowers. The plants bloom from early summer to early fall. The plants are tolerant of a range of moisture conditions and work well in rock gardens.
Climate Zone 9 & Flowering Perennials
Perennials of all sorts do well in U.S. Department of Agriculture plant hardiness zone 9. You can choose from vines, woody-stemmed shrubs and tender, herbaceous plants. And if you live in a small valley where cold air collects in the winter, you may not be able to grow plants designated for USDA zone 9 even if that is your designated zone. Two that grow in USDA zones 8 through 10 include: * Angel's trumpet (Brugmansia x candida), with dangling, trumpet-shaped flowers up to 12 inches long, looks impressive grown in a pot or container placed in full sun on your deck or patio.
* Cuphea (Cuphea 'David Verity'), growing in full sun, has small, 1 1/4-inch flowers that impress with their very bright reddish-orange flowers tipped with yellow. Herbaceous perennials with soft, pliant stems range from fast-growing ground covers to small, mounded shapes and upright forms. Hollyhocks grow in USDA zones 2 through 10 and attract hummingbirds and butterflies.
