Description
With sweetly scented dogwood-like flowers that are so profuse they nearly cover the foliage, the ‘Grandiflora’ Montana Clematis is one that will always have you eagerly awaiting the arrival of its eye-catching pure white blossoms in spring to early summer. The 4 petals surround a patch of pretty, yellow stamens. The flowers are followed by attractive fluffy seed heads in fall. A robust and vigorous grower that will quickly cover large supports such as pergolas, arches, fences or walls to a height of up to 35 feet if the support structure is that tall. Grandiflora Montana Clematis is a winner of the prestigious Award of Garden Merit by the RHS.
Landscape & Garden Uses
Climbing 20 to 35 feet in height and equally as wide, the Grandiflora Montana Clematis is ideal for growing on arbors, pergolas, fences, large trellises, arches, tall obelisks, poles, lamp posts and other structures. A fine addition to Clematis gardens, fragrance gardens, and white theme gardens.
Suggested Spacing: 25 feet apart to cover fences, trellises, and walls
Growing Preferences
The Grandiflora Montana Clematis is easy to grow in a moist but well-drained soil of average fertility and full sun to part shade. We suggest a minimum of 4 hours direct sunlight per day for best flowering and overall performance. Though it tolerates dry periods when established, it will appreciate an occasional watering in prolonged periods of dry weather. See pruning instructions just below.
Clematis Pruning Group 1
Clematis in pruning group 1 flower on last year’s wood and therefore should not be cut down to near ground level (especially montanas, armandii, chrysocoma and gracilifolia which can be killed by hard pruning). They should be pruned as soon as possible after they finish flowering. Avoid pruning them after the end of July, so they have time to produce next year’s flower buds before winter sets in. This group should be lightly pruned to remove all dead and wispy growth. Additional pruning can be performed to remove three or four year old wood to reduce the bulk of the plant. Cut each stem just above a pair of healthy buds.
