Thought I’d share some pics of invasive Chinese wisteria (
Wisteria sinensis) in Missouri
This gets spread by birds and becomes invasive, I have it in a couple of places on our property and have seen it growing in a very remote ‘natural area’ on some state land along the river... so apparently it gets spread pretty easily.
I’m pretty sure I saw this at a garden center the other day, but I was in a hurry so I didn’t confirm that the wisteria they were selling was this species...
....In any case be cautious if buying a wisteria plant, to make sure it’s not this one...
Here are some pics from today... I’ve been trying to contain this patch for a couple years now... glyphosate ( Round up) does not kill the extensive root system... and I’ve been hoping not to use one of the harsher sprays due to root transference concerns.
It’ll grow in full shade of the forest as it chokes out trees... but won’t bloom there...it’ll bloom only in openings where it gets enough sun... but these blooms produce seed that birds spread

This is what it looks like as it spreads on the ground via a vine like root system

Some of the vines I cut to kill the canopy last year ( or the year before) where it was choking out a big black oak

Same on a smaller tree

Most all of this on the ground is new shoots coming up from where I mowed it off last year

Here are two larger vines that I missed previously... they have climbed up and are choking a sapling

Same here, it killed this sapling and used it to climb into the canopy of a larger tree
