Product Description

Clematis montana ‘Grandiflora’ is a deciduous climber and a wonderful choice for early season flowers in the garden, covered in masses of pure white flowers in May and June.

Plant ‘Grandiflora’ anywhere where it can climb and this extremely vigorous clematis will quickly establish itself and begin to clamber up supports, over pergolas and arches and up into trees, cloaking them in a sea of white.

The fast growth makes this an ideal plant for covering unsightly fences and sheds or grown as screening on a trellis.

Montanas should be pruned - if necessary - soon after blooming ceases removing only wood from previous years.  New summer growth will bear next year’s flowers and should be trained and tied in accordingly.

Fully deserving its coveted RHS Award of Garden Merit, you can be sure that this is a proven garden performer, guaranteed to be suitable for UK gardeners at every level of experience. You can therefore plant this in the garden with confidence, for stunning displays for many years to come.

Supplied as an established plant in a 7cm pot, ready for planting, growing to 9m (30ft) high and spreading 3m (10ft).

Plant Information

Top Tips

  • Plant with the crown of the plant 5-8cm deep to encourage new shoots to grow from below ground level.Clematis like a cool ‘root run’ so try and plant so that the roots are shaded. If you are planting in a sunny position, place some pieces of slate or flat stones on the soil after planting or use groundcover plants to keep the roots cool.

Care Guide

  • Feed in spring with a general-purpose feed, avoiding the stems. Mulch immediately afterwards with organic matter such as well-rotted manure, leafmould or garden compost.
  • Water regularly during periods of dry weather in the first few seasons after planting, especially for container plants.
  • Clematis in pots should be given a liquid feed through the summer and early autumn.
  • Montana Clematis should be pruned when necessary soon after blooming, removing only wood from previous years - basically a tidy up when it has finished flowering. New summer growth will bear next year’s flowers and should be trained and tied in accordingly.
