Wisteria sinensis Black Dragon is a wonderful twining climber producing dark purple, cascading, heavily spice scented flowers in May/June. These flowers can reach 2' in length. Its growth is very vigorous and, as it is not self-clinging, will need a strong support.
It is fully hardy but requires a fertile, moist but well-drained soil and prefers sun or dappled shade. It will need pruning twice a year to encourage flowers; two months after the flowers have finished and, again, in mid winter. Unlike its parent, Wisteria sinensis, it will flower after just one or two years.
Wisteria sinensis Black Dragon is a strongly scented dark purple climbing plant with fabulous clusters of pendant flowers produced in May/June just before the foliage appears. It prefers sun but will thrive in dappled shade and is best planted where the fragrance can be appreciated.
It needs the solid support of a pergola, pillar or a wall with vines eyesand wires set at 12" distances. It can also be grown more formally as a half-standard in a tub with a frame. It can look spectacular grown into mature trees when it will need very little maintenance save keeping its vigour in check.
Wisteria sinensis Black Dragon is generally disease free although it can be prone, on occasions, to leaf spot and powdery mildew. Watch for yellowing leaves and honeydew (sticky coating on leaves). If these are seen mealybugs may have infested the plant. Treat with a proprietary control.
All parts of the plant are poisonous and will cause severe stomach problems if ingested. It needs pruning twice a year. Two months after flowering the long shoots should be cut back to 5 or 6 buds from the stem and then, in mid-winter, it should be cut back again to 2 or 3 buds from the stem.
Wisteria sinensis Black Dragon (Chinese wisteria) originates from woodland edges in China where is scrambles over cliffs and into trees. It was introduced by an English botanist and zoologist named Thomas Nuttall who named it after Dr Caspar Wistar a famous physician.
