They are probably multiflora that seeded in.

I have no experience with inherited roses. You could get anything along the spectrum.

What you should do depends on your gardening personality. I would take the latter approach you proposed - that’s much of the fun of gardening - for me. Others may gravitate toward instant gratification.

I would ask the neighbor if the garden had ever been a jewel or treasure. If it had been an average looking yard, then neglected, I might just get a fresh start. Usually neighbors might know if there is grown over masterpiece under the overgrown mess.

Mad-gallica, I think you might be right about these being multiflora! The long thin canes and small leaves certainly remind me of that.

Do a web search for images of "fringed stipules". They look like eyelashes at the bottom of the leaves. It means a rose is either multiflora, or has multiflora ancestry.

Just me but I like choosing my own roses . So I would clean slate it and that is exactly what we when we moved in here .

Here's my pleasant surprise, sometimes it is worth seeing what you've got just in case. But that's just me, I like wondering who planted them and why they were special to them.

My inherited mystery rose was row of pointy sticks in spring but when June came they flowered like this:

Closest ID is the Gallica rose Ombree Parfait. Love them!

I’ve tried multiple times but can’t get the pictures uploaded.

Just want to thank you everyone for your help. I’ll have one that looks like a multiflora removed and give the other bushes some time and see what happens.
