Wisteria Floribunda Alba - Established Plants 150cm+. Wisteria Alba is a large vigorous twining climber, with extravagant flowers that dangle in clusters against the dark green pinnate leaves. The Floribunda Alba have long pendulous racemes of small white pea-like flowers that can reach 20 inches or more.
What to expect: Arriving pot grown in a 5 litre pot. It will have a minimum height including the pot of approximately 150cm. Depending on time of year purchased it will look just like the picture, taken in July.
Planting position: The Wisteria can be grown informally through mature trees or more formally against a house wall. It can also be trained as a free-standing half standard in a container. We would suggest in a sheltered area.
Soil: It will grow in most soils that are moist and well drained. Prepare the ground well by digging in manure or soil improver, especially if planting next to a wall as the area may contain rubble therefore very dry. We would also recommend a bonemeal when planting as this will encourage the roots.
Soil ph: Acid, Neutral and Alkaline.
Suitable for Container planting: It can be trained to be a free standing half standard. It will need regular feeding for the best results.
Eventual height and spread: The ultimate height will be 4-8 metres with a spread of 2.5-4 metres
Pruning: The Wisteria can be pruned back after flowering although this may not be necessary every year. They can have the old and weak growth removed when necessary. It should have the current years growth pruned back to 3 or 4 buds in July or August to promote future growth, although this is not necessary if you are increasing the overall size. Maintain the overall structure to encourage the horizontal growth. Further pruning can take place again in February.
Growth speed: Fast growing
Flowering period: Spring/early summer
Foliage: Dark green pinnate leaves with tiny white pea-like flowers.
Winter Hardy: Yes
Plant in a sunny or semi shaded area with moist, yet well drained soil. Add plenty of well rotten manure or compost to improve the soils fertility. Plant at the same level they are supplied in the pots and water well to settle the area. You will need to provide your plant with sturdy support, either against a wall or pergola or with support wires. As part of your pruning process, tying up specific main shoots will help in defining the structure. During the early years the plant will benefit from regular watering. Once established you will only need to water in dry periods. A feed in spring will encourage flower production.
