Rubus perhaps, like raspberry/blackberry.

probably bird sown ..

and as such.. i would not waste a year or two growing free range bramble.. to find out if it has worthwhile fruit ... berries ...

but that is opinion.. be free ....

Blackberry. Here one like this would be Himalayan blackberry (Rubus armeniacus), which is quite a nuisance plant covering large amounts of real estate with thorny thickets.

Thanks - helpful information. They are quite thorny. I might put a few cuttings in some containers and see what grows as an experiment.

Make it a great day,
Matt
