The best thing to do is to go to a garden center and pick out one you like in flower. Much depends on the space available too but you can get advice on that when you go to purchase.
Can you advise me a of a clematis that I can plant now. Is a west or north facing wall suitable? I live 3 minutes from the sea. Thanks
Any clematis can be planted at any time as they are always supplied in a pot and can be planted out and kept watered once a week until there is good new growth.
