We cut all we can find although the birds do eat the hips. You can make tea from them and they are rich in vitamin C. If you have ever walked into a Multiflora Rose you will respect it, avoid it, chop it, and destroy it if you can...or I do.
They are beautiful from a distance but touted to be the a living livestock fence I certainly can understand how it would keep me out or in. COVERED with prickly thorns, thick growing limbs...a lovely plant.
We are blessed with them here.
See the tiny devil thorns?
Looks just like a rose
but grows far better than any rose I know.
Most of ours are bush hogged but much must be removed by hand along the springs and creeks. Marcy bought me some rose gloves just for that. Leather in the palms and the gloves reach almost to my shoulder and I still can't seem to avoid being torn by these beautiful plants.
Gotta love em. I don't think they will be gone in my lifetime but I can keep trying.
