Double flowered clematis
I have seen a special offer from T&M today for double flowered clematis, at a very cheap price of around £9.00 for 2. I did see these clematis (new) on the t.v. at Chelsea Flower show this year. I can't remember the name of them, but has anyone had any luck with growing double flowered clematis? I am not sure if the flower heads will be too heavy for the plant.
