Overview

It's not unusual for the pendent trusses of lilac flowers to reach up to 50cm in length, so they can really put on an amazing display in the late spring or early summer garden. Often starting to appear on quite young plants, the flowers of this award-winning wisteria have a light perfume, so if it's possible, try to plant it near a seating area or entrance. This plant has been vegetatively propagated, so will flower earlier than those grown from seed.

Care guide

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.

How your order will arrive

Pots and Packaging
Larger pots (2L and above) are wrapped in waxed paper and then attached to a cardboard base so they stay stable in the box. The waxed paper prevents the compost from spilling out and gives the base some added protection from damp compost. For large numbers of plants, pallets may be used for shipping.

Preparation
The nursery will ensure the plant is moist while it's waiting to be picked up. Our quality control team waters the plant before packing them where necessary to make sure that the plant is suitably watered for transport. Plants with long delicate stems are secured with canes to prevent damage.

Plant on Arrival
Typically plants are delivered ready to plant and will take some time to settle, grow and look more like the product image above.
