Lush walls of plants transform an outdoor space into an intimate garden room and create a feeling of enclosure.
Annual vines like sweet peas or black-eyed Susan vine are perfect for this job, needing only slight encouragement to scramble over a fence or trellis. You can also use fast-growing morning glories or scarlet runner beans to turn any fence into a beautiful blooming hedge. Use tall annual vines as temporary green screens to hide unattractive objects from view.
Create a pop-up wall of summer flowers near your favorite outdoor sitting area, so you can watch bees, hummingbirds and butterflies.
Grow Walls of Color with Annual Vines:
- Black-eyed Susan vine. Though this flower is most commonly orange, newer varieties bloom in pale yellow, white or pink. These vigorous vines are easy to grow from seed or purchased plants, and they bloom continuously from midsummer until the first hard freeze.
- Morning glories. Turn any fence into a masterpiece, with dramatic morning glories. Cypressvine morning glory, which produces dainty fernlike foliage and small red flowers that hummingbirds find irresistible, is the easiest to grow.
- Sweet peas. Plant these fragrant vines near windows often opened during the day. Sweet peas stop blooming by late summer, however, so plant a few scarlet runner beans when peas are 12 inches tall to continue the show.
- Beans. Blossoming varieties such as scarlet runner beans and hyacinth beans have a coarse texture compared to other annual vines, but their exuberant growth makes them ideal if you want to grow a high green screen. These vines climb a 10-foot trellis and keep on going, so they are the best annual vines for tall tripods or string trellises attached to the sunny side of a building.
If you are thinking of adding clematis or another perennial vine to your landscape, test the site by planting an annual vine for a season.
