A twining and vigorous climbing plant, these pinnate leaves are composed of eleven to nineteen oval, lanceolate leaflets. The foliage is cut and the silhouette of the silver gray bark makes it a very decorative plant for all seasons.
In May, fragrant, blue to purple flowers appear. They bloom in very long clusters of 30 to 50 centimeters long. The flowers offer a honey scent.
Very fast growing vine, it supports pruning and can be grown as a climbing plant on different artificial or natural supports but also grown as a tree planted in an isolated place or in a pot.
The use of fertilizer is not necessary but if you wish to use one, choose a fertilizer rich in phosphorus which will promote flowering.
Tree Growing Guide:
If your wisteria has only one stem, stake it. If it has several stems, braid them around the stake, they will fuse together naturally over time.
Let the plant grow to the desired height. Prune the trunk and remove all the stems and leaves that grow on the trunk except the last branches at the top. These as they develop will form the framework that you will prune regularly thereafter.
