Amethyst Falls Wisteria is not the aggressive type that destroys trees and pergolas. It’s a first year flowering variety that grows up to 30 feet. It’s a somewhat fast grower. Wayside Gardens has it on their best seller list.
It’s providing shade for the shade perennials.
Its blooms last a very long time. I’ve seen it blooming for over a month.
Give it something strong to grow on.
