Popular for its double flowers, Wisteria floribunda Black Dragon (also known as Wisteria floribunda Violacea Plena) has violet purple, pea-like double flowers that hang on long racemes in summer. Pinnate foliage emerges bronze in spring, maturing to bright green then buttery yellow in autumn.

Ideal for growing against a wall or over a pergola, Wisteria Black Dragon can grow to 10 x 4 metres in 20 years and prefers moist but well drained soil and a position in full sun, though dappled shade will be tolerated. This Double Purple Wisteria plant is a beautiful variety, offering great seasonal interest.

All our Wisteria are grafted (rather than cuttings) so ought to flower earlier.

Planting Advice for Wisteria floribunda Black Dragon Tree

Our pot grown Double Purple Wisteria can be planted at any time of the year. Start by removing all weeds and grass within a metre of your intended planting hole, which is ideally next to something the Wisteria can climb up. Dig a square hole as deep as your root mass and approximately 2x as wide. To help your tree establish more effectively, especially if you have poor soil, we advise sprinkling root grow in the hole.

Take the pot off and gently loosen the roots, then place into the planting hole. Mix 50% of the original soil with 50% compost, then fill in the hole and firm around gently, making sure not to bank the soil up around the collar. For further information, visit our help and advice section.

Aftercare of Wisteria floribunda Black Dragon Trees

If you’re planting in spring, summer or dry weather, water well and regularly for the first few months. Make sure to keep an eye on young Double Purple Wisteria and increase watering if there are extended periods of hot or dry weather. If you’re planting in autumn, you may only need to water your tree a little. We stock a range of irrigation kits, suitable for a variety of planting schemes.

Once planted, it is important to keep the area free of competing weeds and grass for the first couple of growing seasons.

Pruning Advice for Wisteria floribunda Black Dragon

Wisteria plants have a reputation for being high maintenance when it comes to pruning, but this is not the case! When pruned at the correct times, Wisteria is easy to control and a pleasure for everybody.

Wisteria floribunda Violacea Plena needs to be pruned twice a year. - in July or August and then again in January or February. In summer, after flowering, prune the green, whippy shoots from the previous year’s growth. This encourages flower production and helps to control the overall size. In January, remove up to half of the previous year’s growth, leaving just a few buds on each stem.

Below are definitions of various forms, which refer to the shape of the tree defined by the pruning it has received. For more advice, please contact us.

Single Stem / Pruned and shaped: Classic shaped tree with a single stem that has had pruning to help create a beautiful, natural shape.

Top grafted: A height noted next to this form refers to the length of clear stem, which will not grow taller. Only the head of branches will develop. Top grafted trees do not require complicated pruning and are ideal for small spaces.

Multi Stem: A multi stem tree is has two or more stems arising from or near ground level, growing from one root system. Take care to buy a true multi-stem like all ours and not those that are 3 saplings in a pot to cheaply imitate them.

Feathered: A feathered tree has branches from the bottom of the trunk all the way up. These branches can be removed if a clear stem is required.

Bush: A plant with many stems low down, rather than one clear stem.

Climber: A plant that is a natural climber and will be delivered usually running up a bamboo cane, ready to position in the garden.

Standard Tree: A more mature tree with an upright clear stem of approximately 1.8m-2.0m (measured from the soil to the lowest branch), which supports a branched crown. Standards are available in different forms relating to their girth size (circumference of the stem measured 1m above soil level), not height.

Standard  either 6-10cm or 8-10cm girth, approximately 2.5-3.0m in height
Premium Standard  10-12cm girth, approximately 3.0-3.5m in height
