Answer: There are two vines that I'm familiar with that might be considered slow growing: Hydrangea Anomala Petiolaris (climbing hydrangea) This is a self clinging vine that produces magnificent, showy white fragrant flowers. It's slow growing until established; then grows more quickly, but can be pruned to maintain size. Or, Schizophragma Moonlight (moonlight false hydrangea) A slow growing climbing vine with pewter blue leaves veined in pink and green. Large white flowers in July. Grows in full sun to light shade. Hope one of these is just right for your garden.
