Weeping perennial plants add the finishing touch to borders, rock gardens, walls and planters. Weeping perennials that bloom add another layer of color and texture to the garden design. Select plants with evergreen foliage and they will provide interest all year long. Try weeping perennial blooming plants as a constant base in tub planters, and replace taller plants during the season to refresh the container.
Evergreen Candytuft (Iberis sempervirens)
Growing about 10 inches high and spreading up to 35 inches, candytuft creates billows of small white flowers. It is covered in blossoms for several weeks in the spring and early summer. After blooming, candytuft's evergreen foliage makes an excellent contrast for other flowering plants. It is a drought tolerant plant that can be used wherever a weeping perennial is needed. Lightly prune candytuft after the bloom period to encourage spreading and increased flower production the next season.
Trailing Twinspur (Diascia barberae)
Twinspur has been popular in English gardens for many years, and it is now becoming popular in American gardens. Trailing twinspur is a low-growing plant about eight inches high that spreads to two feet wide, spilling over edges of pots, fences and borders. It is a tough little plant that keeps blooming from late spring until fall. Twinspur is not particular about soil type or pH, and it requires little care once it is established. Deadhead spent flowers regularly to keep the plant blooming.
Ground Morning Glory (Convolvulus mauritanicus)
Not to be confused with invasive morning glories, Convolvulus mauritanicus forms spreading, mound-like trails of foliage. The foliage is dark green, a lovely complement to the light blue or mauve flowers. It is often used as a ground cover, but creates a lovely cascading effect when used in a border or along a retaining wall. It is popular as a weeping plant for large planters and hanging baskets. Ground morning glory may be treated as an annual in severe northern climates, but where it winters over it is evergreen. This plant is drought tolerant.
