Description
Truly mesmerizing in bloom, the Killian Donahue Clematis features abundant 5 inch flowers that dramatically change colors throughout the long blooming season from late spring throughout summer. The 5 inch diameter flowers open ruby red at the center turning to orchid with brilliant fuchsia bars and finally to lavender with a pink bars. The various colors can appear on the vine at the same time. Burgundy-tipped white anthers on every bloom are an extra bonus and a magnet for butterflies and hummingbirds. At 8 to 10 feet high this one is perfect for fences, arches, posts, railings and tall trellises or obelisks.
Landscape & Garden Uses
Growing up to 8 to 10 feet tall and 2 to 3 feet wide, the Killian Donahue Clematis is ideal for growing on a fence, tall trellis or obelisk, mailboxes and other posts, arches, rails and other structures. Also a fine selection for growing in pots, planters or tubs that can be situated on patios, decks and around other outdoor living spaces where the amazing flowers can be viewed from close up. A fine addition to Clematis gardens, cut flower gardens, and cottage gardens.
Suggested Spacing: 2.5 feet apart to cover fences, trellises, and walls
Growing Preferences
This Clematis is easy to grow in a moist but well-drained soil of average fertility and full sun to part shade. Though it tolerates dry periods when established, it will appreciate an occasional watering in prolonged periods of dry weather. Make sure not to plant this one too deep as it tends to smother the plant. See pruning instructions just below.
Clematis Pruning Group 2
Clematis in Group 2 consist of all the early, large-flowered hybrid clematis that bloom in late spring or early summer and maybe again in late summer. Clematis in this group should be pruned lightly in late winter or early spring. Pruning consists of removing weak and crossing shoots then thinning down the plant to a structure of evenly spaced one and two year old stems. Cut each stem just above a pair of healthy buds. Plants in this group have the tendency to become bare at the base as they mature. You can under-plant with small shrubs or perennials to help conceal the bare stems. Alternatively, you can often force a flush of new growth from the base by cutting the vine back to 18 inches immediately after the flush of bloom.
An alternate method of pruning Group 2 clematis is to prune only every three or four years. In this case, the clematis should be pruned as described for Group 3 clematis. This will produce a weak first flush of flowers in the summer after pruning.
