I've been making a determined effort to get rid of all the chokeweed in the yard and, among the chokeweed is a plant that looks very similar. Triangular leaves, climbs everything like a vine, etc. However, it has purple flowers and green berries forming. The "Seek" App on my phone says it is "Bittersweet Nightshade". Is this plant invasive? Should I be pulling it out along with all the chokeweed?
In BC, yes, it is invasive. The berries will ripen red, and the seed dispersed by birds, in the autumn. It is native for me, so I don't remove it here :-)
