What is this vining plant I found climbing my Casa Blanca lilies? Transplant it or trash it? The stems are covered with very short prickliest that stick to your hands, clothes and other foliage.

Hops (Humulus lupulus)

Thank you! I don't know how it found its way into my patch of suburbia! Not brewing beer any time soon so it's got to go!

Invasive, accidental, brought by birds or wind? I'm not sure which.
