White Anemone Clematis Plants

Clematis Montana 'Grandiflora' Plants

'Grandiflora' produces a dazzling show of pure white blooms that really cover the plant in late spring (May-June), with a smaller second round later in good conditions. Flowers (up to 7cm in diameter) are simple and elegant, four white petals arranged in cruciform around yellow anthers at the centre.

The variety is listed as unscented, but in full sun a delicate fragrance can be detected. A vigorous and very hardy perennial, this deciduous climber is perfect for exposed sites. Can reach a height of 10-12m.

As a white flowering variety, Grandiflora does not fade in the sun like colourful varieties.

Look out for:

Aphids and caterpillars are fond of the young shoots

All clematis can be affected by Clematis slime flux, a bacterial infection of damaged tissue that can kill large specimens almost overnight. Can be pruned out if spotted early.

Blooms can develop a greenish tint in shade/cold weather.

Trivia:

Introduced from North India by Mr Veitch around 1844, it was awarded the RHS Award of Garden Merit in 1993. Chartwell House, the family home and garden of Sir Winston Churchill, has a fine display of Grandiflora.

How to grow Clematis Montana 'Grandiflora':

Clematis Montana 'Grandiflora' can be grown easily following the Clematis planting notes.

Give it a deep, moist spot to bury its roots into and space to clamber into the sun.

Will tolerate north-facing aspect and coastal conditions.

The soil needs to be well drained (it won't tolerate water logging).

Needs a strong supporting structure - with age the plant can become very heavy if left unpruned.

Final height of up to 10m makes it well suited to scrambling through large trees or covering high walls/fences - either plant it in a spot where you intend to prune it after flowering to restrict size, or give it room to ramble to its heart's content!.

Pruning group 1 - no regular pruning required. If you want to reduce their size, prune immediately after flowering.

All clematis like a mulch of well-rotted manure or garden compost in late spring - they are hungry plants.
