continent-of-wild-endeavor:

A nice climbing rose of some sort, by the margin of the woods near the picnic area. As I moved my hand away after admiring it, it stabbed me right in a papercut on my finger, so I left the encounter bleeding. Thanks.

Is it wild? Leftover from previous cultivation of this area? Invasive? I don’t know much about roses, beyond the ability to look at this and say that it is one.

EDIT: Confirmed on wildflower walk today – it’s the invasive one. Multiflora rose, aka Rosa multiflora.
