Wisteria Sinensis 'Purple Chinese Wisteria' is a vigorous and popular deciduous climber here in New Zealand. The foliage is usually bronze when young. Purple-mauve fragrant, pealike flowers open in compact, pendulous clusters in Spring, and give a glorious display of colour. It is a native of China, and it flowers best in full sun.

Origin: Asia. This woody deciduous vine can climb 20-30 feet. The leaves are divided into 11-13 pointed leaflets. In the spring while the leaves are budding out, the vine produces foot long clusters of fragrant purple flowers. These clusters hang below the foliage, creating a spectacular show.
