With its luminous foliage and summer lacecap flowers, Schizophragma hyd. 'Moonlight' brings a refined look to shady vertical spaces. Your Japanese Hydrangea Vine 'Moonlight' is a deciduous, woody climbing vine that attaches to flat surfaces with holdfasts, making it ideal for masonry, fences, pergolas, or large tree trunks.
In time it can reach 20-30 feet tall (240-360 inches) and spread 10-15 feet (120-180 inches). It is often slow to establish, so plan for a few quiet seasons while roots settle in. Once it starts climbing in earnest, it will fill in with heart-shaped, silvery blue-green leaves and broad, flat lacecap clusters of creamy white flowers through summer.
Give it rich, humus-y soil that stays evenly moist but drains well. It performs best in partial shade to full shade, and it tolerates deep shade; in cooler climates it can take more sun if you keep moisture consistent. Mulch to moderate soil temperature, and water during dry spells, especially while the vine is young.
Prune only as needed to shape or control size, typically in late winter to early spring. Provide a sturdy, flat support surface from the start and allow room at the base so air can circulate and you can water easily. If you want quicker coverage, train a few main stems upward and tie lightly until the vine is securely attached.
