Description
- One of the very best Japanese wisteria varieties, 'Royal Purple' is long-lived, vigorous and fully hardy, making it an excellent choice for British gardens.
- Long, lilac-purple flower sprays bloom at the end of spring and the start of summer, instantly transforming the surface your wisteria is trained against.
- An ideal choice for any cottage garden planting scheme; rustic charm? This wisteria offers it in sumptuously-scented spades!
- The stunning flower racemes are set against a lush, light green backdrop of pinnate compound leaves, which fall in winter and expose fantastically architectural woody stems. In other words, this is a climber that offers true year-round interest.
- A wisteria of many names - including 'Black Dragon', 'Russelliana' and 'Kokuryū' - 'Royal Purple' looks utterly fantastic when trained up a stone (or brick) wall, fence or free-standing pergola.
- A deserving recipient of the RHS Award of Garden Merit.

How to grow
How to grow
Good pest and disease resistance
Might be affected by aphids, spider mites and scale insects, and from a disease perspective, it can be susceptible to leaf spot and mildew.
Water regularly when first planted
Water your 'Royal Purple' wisteria well when first planted, particularly during prolonged periods of hot and dry weather. After the first couple of years, however, the plant should be established well enough that it only needs watering lightly (if at all).
Full sun to partial shade
For the best flowers, full sun (at least six to eight hours of direct sunlight per day) is desirable. That said, 'Royal Purple' will still grow nicely in part shade.
Any fertile, moist, well-drained soil
If your soil is especially heavy or is prone to becoming waterlogged, then ensure you mix in plenty of organic matter and perhaps even gravel or horticultural grit to help improve drainage.
Feed every spring
Apply a general, well-balanced fertiliser every year during spring. This encourages greater flower growth.

Best plants you will ever get online
I have ordered plants from them twice this year. They arrived well packaged, on time and looked strong and healthy. I feel the staff from Roots plants deal with their plants and customers with passion and care. I can’t wait to order again, price is good as well.
Highly recommended all round
Delivered quickly, perfectly packaged and the tree was in excellent condition. Really healthy and taken to the garden with no problems. Can't recommend highly enough. 5 stars isn't enough!
Satisfied customer
Unlike other online sellers, this company are well ahead in the quality stakes. My plant arrived promptly as per their promise and the plant was much more established and healthy than I had expected. It’s the second time I have ordered from them and I have faith in their promise. Excellent service.
A really good quality tree
A really good quality tree, delivered on time and very well packaged. But the emailed planting advice and supporting information was what really impressed me. Thoroughly recommended.
Exceptional quality
The quality of the plants was exceptional, unlike ones I have had before from local garden centres. Thank you so much. I will definitely be using you again.
Marvellous!
Marvellous service, great plants and fast delivery. Very useful information on how to care for the plants I bought. Easy to use website that makes it far too easy to overindulge in fabulous plants 😂🌱
