Hi, everyone! <wave> I am new here...live in the country north of Vancouver, WA....
I have always dreamed of having a Wisteria vine, but, never lived anywhere long enough to plant one and own it over the years. Six years ago we bought a country property and VOILA! the previous owner who built the house also planted a Wisteria vine in 1986. I love it and especially it yummy fragrance and gorgeous lavender flowers. I love how it has climbed up the side of the deck and up to the roof of the carport. I have never regretted having this Wisteria. It is easy to prune and cut it back when needed if you keep a watch on it. It is amazing how fast the fronds reach out. This Wisteria has never spread underground at all.
Go ahead and have your Wisteria and enjoy its wonderfullness
All parts of Wisteria, except for the blossoms, are...toxic to humans and to animals (dogs, cats, horses, etc) so be careful where you plant Wisteria. I also suggest that you do not compost any part of Wisteria.
