Is Wisteria Slow Growing In Zone 5?

Question

Hi! I am hearing conflicting advice when it comes to wisteria in my zone 5b! I have been considering growing amethyst falls wisteria or blue moon wisteria up a pergola on my property. I am concerned about the speed of growth of this plant. I was told that in my zone it will grow a lot slower…is this true? I don’t want to plant something that will overtake my structure quickly and ruin it!

Answer 1

I haven't seen any research that confirms that it will grow more slowly in your area. I think you may just need to find a slower growing variety, such as Wisteria frutescens, but your location is likely ideal for wisteria growth. Here are a few articles that may help you as your wisteria grows:
