I have just received 2 climbing roses as a gift - Dublin Bay and Penny
Lane - and am trying to find the best position for them. At the back of one
of our flower beds we have a 2.5ft ornamental wall beyond which is a paved
area. If I were to plant one at each end of the back of this bed, would they
"trail/ramble" along the wall or do I need to find somewhere where they can
climb more vertically

Would appreciate any advice
