You can grow Clematis through hedges, Janet - I'm sure Charlie will
recommend which are best but my fil had Mde. Le Coultre going through
Camellias in his Camellia Walk and as it flowered after they did, the effect
was spectacular and confusing to the unwary! ;-)


Well Hawthorn needs cutting twice a year Sacha so I didn't think that
clematis would be feasible. I generally cut late may and again in late
September. If it would take a clematis what about the competition at
soil level?
