My garden faces SW. There are mature trees at the very bottom of the garden. The side of the trees that faces me gets sunshine early morning and late afternoon/evening from about April to October. The ground at the bottom of the trees is in permanent shade. It's by no means bare, though. I have shrubs and bulbs there, as well as plenty of weeds.
Could I grow wisteria and clematis up the trees? Would they flower on my side?
