Size and Method of Climbing
A fast growing, deciduous, woody vine that typically grows 30 to 50 feet high. It is a vigorous clinging vine that clings to surfaces with holdfasts.
Clinging vines attach themselves directly to a surface by means of holdfasts (adhesive discs) or by small aerial roots. This type of vine grows best on a flat surface, such as stone, masonry walls and wood.
Best grown in average, well-drained soils in full sun to part shade. Tolerant of full shade, but best fall color occurs in sunny locations.
This species has shown some aggressive tendency in naturalize areas or when minimally managed in cultivation.
