I planted them a few years back.
Most commercial roses have a wild rose root stock with something else grafted to them. The reason is because wild roses have more hardy roots that are more disease resistant. Wild roses grow on their own root stock, so there's no worries about killing the grafted rose. I don't really do anything to mine. They aren't bothered by mold, mildew, or pests so I don't ever have to treat them with anything. You can give them some flowering shrub fertilizer in the spring if you want, but I generally don't and they still bloom profusely. Mine are getting ready to burst with flowers probably by next week.
As far as mine goes, they are far from thornless but their thorns aren't big and nasty like most hybrid tea roses are. I usually don't even wear gloves when I'm pruning them back and I wouldn't dare do that with a hybrid tea. You wouldn't want to jump in the middle of them, but just brushing up against them is no big deal. I have them planted in my front flower beds with my entryway sidewalk running through them. I do believe there are thornless versions of wild roses, but I couldn't tell you what those are.
