With this purple perennial border trio, youve got six months of flower and beauty. First comes the clematis which blooms from late spring, with the thalictrum frothing up all round it by mid-summer and both pierced through by the ever-reliable and splendid Verbena bonariensis right into late autumn. We love this combination growing along one side of our Perennial Cutting Garden path, still as good today from its planting five years ago.

This collection contains:

• 3 x 9cm pots of Thalictrum delavayi
• 3 x 9cm pots of Verbena bonariensis
• 1 x 2 litre pot of Clematis x durandii (Integrifolia Group)
