Description

A wonderful white flowering Wisteria, Wisteria floribunda 'Alba' is a really beautiful alternative to the usual flower colours. The summer-flowering racemes are long at up to 2ft (60cm) and the white flowers have the slightest suggestion of lilac. Bright green foliage emerges bronzed in spring and turns yellow in the autumn.

Wisteria floribunda 'Alba' is a less vigorous climber than most Wisteria, growing to 7 x 4 meters in 20 years. It is suited to any free draining soil and full or partial sun is ideal but some shade will be tolerated. 'Alba' is ideal for growing over a pergola or against a sunny wall, but will equally do very well romping up the trunk of a tree to seek out the sunshine.

As with all our Wisteria, this Japanese White Wisteria is grafted and tends to flower at a younger age than those grown from cuttings.

Planting Steps

1Preparation

Pot-grown plants can be planted at any time of year, whereas bare roots need to be planted between November and March.
Clear weeds and grass within a metre of the planting hole.
Dig a hole as deep as the root mass and twice as wide.
To help your plant establish more effectively, sprinkle Rootgrow in the hole.

2Planting

Gently loosen the roots and place into the planting hole.
Ensure the top of the plant's compost is flush with the level of the surrounding soil and the graft union or collar of the tree is above ground level.
Mix 50% of the original soil with 50% compost.
Fill in the hole, firming the soil gently.

3Last Steps

Water generously around the base of the plant.
If you are planting either a single stem tree or mature standard tree, we recommend adding a staking kit and rabbit guard.

Aftercare Advice

Wisteria require a good watering regime for a couple of years whilst they establish. Water well and regularly through spring and summer, increasing in hot or dry weather. If planting in autumn, you may only need to water a little. It is advisable to keep the area free of competing weeds and grass during this period.

Wisteria should be pruned twice annually—once in February when it is dormant and once in August—in order to maximise flowering and help keep it under control. The idea is to encourage the development of short, flowering-bearing spurs and reduce the amount of vigorous, leafy growth.

In February, start by removing any dead, diseased or damaged branches, right back to the main branch. Tie in new growth to extend the main framework and cut back summer side shoots to two or three buds from the base. As there are no leaves on the wisteria at this time of year, it'll be easier to see what does and doesn't need pruning.

In August, after flowering, cut back long or whippy green side shoots of the current year's growth back to 20cm (about five leaves from the main stem). If there are any dead, diseased or damaged branches, these should be removed. If your wisteria is young, select a few strong shoots to tie onto your climbing support. On an older wisteria, simply prune side shoots back to your framework of strong shoots.

To keep them happy and healthy, wisteria can be fed every spring with a general purpose fertiliser. Feeding with a high potash fertiliser or a flowering shrub feed (such as a rose feed) will encourage flower production.
