Would this be a weed??
Yes. That is an invasive shrub. In fact, it looks to be Solanum aviculare or the Kangaroo Apple. It is quite beautiful, but very toxic.

I have two kangaroo apple plants, wondering if you take the seed pods and will ripen off the plant? Because I live in a part of the world where we do get frost. Thank you Cathy
I would definitely only take fruits that fall from the plant, naturally. They are toxic until they do, and the seeds will not be ripe. whether it is chilly weather or natural drop, I'd wait to take them.
