Clematis montana 'Grandiflora'
- Clematis montana 'Grandiflora' is a highly vigorous deciduous climber renowned for producing an astonishing profusion of large, pure white blooms during the late spring and early summer.
- Amidst its attractive mid-green foliage, this clematis often emits a delicate, sweet vanilla-like fragrance that beautifully scents the surrounding garden breeze.
- Because of its exceptionally rapid and expansive growth habit, this clematis is ideal for quickly concealing unsightly walls or sprawling over large pergolas.
- Unlike later-flowering varieties that require hard winter cuts, this clematis needs only minimal pruning immediately after it finishes blooming to comfortably manage its extensive size.
- As an incredibly resilient and unfussy garden performer, Clematis montana 'Grandiflora' thrives reliably in mostly sunny to partially shaded locations while preferring its roots to remain cool and moist.
