Outstanding Qualities

This evergreen climbing hydrangea is an elegant and graceful clinging vine with year-round interest. The stout new growth emerges with bronzy tones that contrast nicely with the older, deep green foliage. Although this vine can be slow to reach blooming age, it is well worth the wait. In early summer, huge rounded flower buds open to an attractive lacy, white bloom reminiscent of the familiar shrubby, lacecap hydrangeas. It is a surprisingly vigorous vine and is excellent for covering unsightly retaining walls and harsh rockeries. The side branches reach out from the main trunks, creating a layered and graceful three-dimensional effect. It clings by means of aerial roots. As it becomes a large, heavy vine with age, be sure to provide strong, long-lasting support. It is striking when grown up tall evergreen trees, where it can brighten a woodland setting. One of the few vines that blooms well in shade, it also can be used on a north-facing wall or fence. This native of Taiwan and the Philippines is not common but is worth seeking out.

Culture Notes
This evergreen climbing hydrangea will grow well in full sun to dappled shade with well-drained to sandy soil. Provide regular water for the best growth and flowering. It will eventually become a large plant, give enough space to fully develop over the years. The vine is often slow to settle in and it can take two to three years before it begins to grow vigorously. It is also slow to start blooming- five to seven years may pass before it produces its first bloom. Those who are patient will be rewarded with one of our most beautiful vines.
