USDA Hardiness Zone (F): 5 (-20 to -10 F) Season of Interest: Autumn This Japanese hydrangea vine cultivar is a deciduous, woody-stemmed, climbing vine which is valued for its silvery, blue-green, heart-shaped leaves (3-5" across) and large, flat-topped, lace cap hydrangea-like clusters (8-10" across) of creamy white flowers which bloom for 6 to 8 weeks in summer. Foliage turns yellow in fall. Attaches to and grows up flat vertical surfaces such as masonry walls by stem-borne adhesive rootlets. Reddish-brown stems provide some interest in winter. Sow late winter to early spring in a greenhouse. Germination is usually fair to very good. Prick out the seedlings into individual pots once they are large enough to handle and grow them on in light shade in the greenhouse for their first winter, planting them out in late spring or early summer. Culture Best grown in rich, medium moisture, well-drained soil in part shade to full shade. Prune in late winter to early spring. A single plant will eventually grow 30' or more wide, though for quick coverage, space 6-9' apart. Please message me with any problems before leaving negative feedback, I am sure we can work it out!
