I have a few clematis to plant over 2-3 arches and trying to look ahead to their pruning requirements.
I believe these are all group2 and would therefore be ok together;
Then I have pruning group3 ;
And group 1;
montana tetra rose
These are in pots and not yet attached to the arches.
I have the following planted in the ground;
I have planted against a fence, but would consider moving;
bee's jubilee (group2)
And already on one arch;
Pamela Jackman (group 1)
this is with solanum glasniven (movable) same side as PJ and rose Generous Gardener on the opposite side.
There's an ivy knocking about as well but I doubt I'll use that.
Sorry for the long list!
Your ideas of combinations over a total of three arches would be most helpful.
