Buy Wisteria floribunda 'Yae-Kokuryu' Japanese wisteria ( syn. Wisteria Black Dragon / Wisteria Violacea Plena): Pendent clusters of lighly fragrant, pea-like, violet-blue flower

This climber is deciduous so it will lose all its leaves in autumn, then fresh new foliage appears again each spring.

  • Position: full sun or light, dappled shade
  • Soil: fertile, moist, well-drained soil
  • Rate of growth: fast-growing
  • Flowering period: May to June
  • Hardiness: fully hardy

    Pendent clusters of lighly fragrant, pea-like, violet-blue flowers with white and yellow markings in May and June. This vigorous wisteria is perfect for training over a sunny wall or stout pergola. To enhance flowering it requires ample space for the roots to 'run' and pruning rigorously twice a year.

    This plant has been vegetatively propagated, so will flower earlier than those grown from seed.

  • Garden care: To get lots of flowers, the twining stems need pruning twice a year - once in summer (about two months after the flowering has finished) and again in mid-winter. To train your wisteria against a wall, the wall will first need a network of stout horizontal wires, attached at approximately 30cm intervals. After planting, prune the leading shoot of your wisteria back to approximately 90cm above ground level and remove any side branches as this will encourage a strong new leader to form. In the summer of the first growing season, tie the leader in vertically and choose two new lateral shoots on either side of the leader. Tie these onto the wires at a 45 degree angle. Any smaller shoots coming from these lateral branches should be cut back to two or three buds. In the first winter, cut back the leader to a bud approximately 75cm above the highest lateral branch. Gently untie the lateral branches and prune them back by about a third, then re-tie them onto a wire so they are nearly horizontal. In subsequent summers (and until the plant has filled the allotted space), tie in the leader as it grows and choose two strong laterals to form the next tier. These should then be tied in at a 45 degree angle and as in the previous year, any smaller shoots coming from these should be cut back to two or three buds. In subsequent winters cut back the leading shoot as before and cut back and re-tie the new laterals to a near-horizontal position. The older laterals can be cut back by about a third of their total length. Once the plant has become established and reached the desired height, keep tying in the lateral stems as they spread out. In summer, cut back the wispy stems on both the laterals and sub-laterals (the side shoots from the laterals) to about five or six buds from the main branches. In winter, cut back these stems even harder to within two or three buds of the main branches. These form the short spurs that will go on to produce flowers in the following spring.

Can this plant be grown in a pot.

Havent got one

Hello, These can be grown in large pots provided they are kept well fed and watered, however it will restrict its growth considerably, so wont get nearly as big as if it were planted out in the ground.


Hello I purchased a wisteria from you last spring and planted it at the same level as it was in the pot, i.e.with the graft above the soil, however I have just been planting roses where the advise is to plant the graft below the soil. Should I have done this with the wisteria? Cheers Jennifer Bishop


Hello there No you were right to plant your wisteria at the same level as the pot,- most grafted plants are planted in this way. Roses are an exception with the graft planted just below the soil level. Hope this helps.

Dear Plant Doctor, I grew a Wisteria against a shaded north wall. It grew well for some eighteen months to two years and then quite suddenly died. I thought I would try again and plant another another. Any ideas as to why the first might have died so that I can avoid similar in the future. Might it be the position?


Hello there Not many plants will survive a northfacing shaded wall. I cannot say exactly why your wisteria died but these climbers normally do best in a sunny, warm site. I have attached a link below to climbers that will tolerate these conditions. http://www.crocus.co.uk/plants/_/climbers/plcid.15/vid.186/vid.11/ Hope this helps.

Hi Roughly how tall are these? Thanks Sam


Hello, They will all be slightly different, but as a very general guide, I would expect them to be around 60 - 90cm tall.


Hello! About a month ago my partner got for me a Wisteria Black Dragon from you. I was so very happy and really pleased at how tall the plant was and how well packed it had arrived. It was planted 24 hours after arrival in a mixture of compost and soil and watered. My question is, how soon am I supposed to expect growth? It looks exactly as it looked when it first arrived (bare twig with tiny, tiny buds...)and it has been watered about once every week, generously. Am I doing something wrong? Am I just being overly anxious? It is still cold in my neck of the woods (east midlands) and it has been very windy. Perhaps these have been contributing factors..? Any suggestions will be highly appreciated. Kind regards, Maria. :)


Hello Maria, Wisterias are usually very late into leaf, so you will need to give it time. Normally the flowers appear first, followed closely by the foliage, so I would not expect to see any signs of growth until late May or mid-June.


Wisteria leaves are falling off..... Hello, We received our delivery last Thursday and whilst we are very happy with the service and the quality of the plants, unfortunately we are worried about the Wisteria floribunda 'Alba'. It arrived with no leaves and the only ones left were yellow and have fallen down. Is this ok? I look forward to hearing from you

Hi Helen, Thanks for the putting my mind at rest and for your email - really really helpful. I will keep an eye on the plant and get back to you in Spring if the Wisteria goes from being sorry for itself to being depressed in our garden! Thanks again,

Crocus Customer Services

Hello there, Thanks for sending the picture. I have had a look and the plant does look pretty sorry for itself, but this is exactly how I would expect the Wisteria to look at this time of the year. The few remaining leaves will soon drop off and you will be left with a very bare twig throughout winter. I would recommend you plant it out as normal ,and as I have added some notes to your order about your concerns, get back to us in spring if it fails to put on lots of new growth. All the Wisterias we sell are expensive as we only sell grafted plants, which is a highly skilled and laborious process, but ensures that the plant will flower much earlier than those that are not. I hope this helps. Helen Plant Doctor

Mature Wisteria Hi The front of my south facing cottage is covered with a large, probably 50 year old wisteria. We are having alterations to the cottage and have tried every solution to save the wisteria, but eventually it seems that it is just to difficult to alter the building with it in place. I would like to replace it (don't know the variety) with a maturie/ish plant. Is it possible to buy a plant which has already flowered and how mature a plant can be transplanted. We live in Cumbria. I welcome your advise. Kind regards Sandra

ian & sandra wallace

Hello Sandra, We sell grafted Wisterias, most of which have already flowered, or are just about ready to. They are commonly available and some specialist nurseries will have very mature plants, which will have been grown in a pot so are happy to be transplanted. I hope this helps. Helen Plant Doctor

Wisteria Black Dragon - is it grafted? Dear Sir/madam, I am interested in a purchasing a Wisteria Black Dragon (floribunda 'Yae-Kokuryu). I note from your website that you offer this plant; could you please advise if they are grafted or rootstock. Kind Regards Stuart

Stuart Wood

Hello Stuart, All the Wisterias we sell are grafted, so they will flower earlier than those propagated in other ways. I hope this helps. Helen Plant Doctor
