I am very proud to announce that my Wisteria has got flowers this year!
I am living here since 2010. The poor Wisteria was cut down to the ground when I moved in. I did not cut it since 2010, and it became a better-grown climber. At the other side of my back fence, where it grows, are big waste bins. Every morning people from the workshops open the lids against the fence breaking off the new growth. There never were any flowers.
This year the climber gave me at least 20 strings of flowers.
It is hardy in USDA plant hardiness zones 5-9, and prefers moist soils. It is considered shade tolerant, but will flower only when exposed to partial or full sun. It will also flower only after passing from juvenile to adult stage, a transition that may take up to 20 years. It can live for over a hundred years.
