I'm not sure about whether or not stinging nettle is invasive. It's probably considered a weed to many and one plant found might be considered invasive.
As the name implies, the plant will sting you when touched.
BUT it has lots of useful qualities. The nutritious young leaves can be steamed to deactivate the sting. I've never tried it but have heard its' delicious. It also has a long history of effective medicinal uses.
I would love to grow the plant for any one of its benefits.
