“Nearly Wild” roses

“Nearly Wild” roses

I'm looking for resources on taking care of Nearly Wild roses. I'm doing a web search, but I'm mostly just finding places trying to sell them. Mine are not happy where they are living. I thought it got enough direct sun, but apparently not, since the roses are crawling along the ground towards the very sunniest part of the yard. (I didn't plant them in the sunniest part because it's where we need to walk to use the hose, but I think I have sunnier places to put them.) So I went to Home Despot and asked for advice on transplanting them, which turns out to be a lot harder than I thought. Since you see wild roses growing all over the place here, I didn't think they would be so high-maintenance. Also, they're producing rosehips and I'd like to try starting new plants from those if I can, but all I can find on the interwebz is how to make tea out of them. ANYWAY, long story short, I need to know more about taking care of these and I'm having trouble finding resources. Suggestions? Also, one site said they don't "sucker." What does that mean? I'm in zone 4a, if it matters. Domestic roses tend to be high-maintenance here, but the woods are full of wild ones. If I could plant actual wild roses I would, but "Nearly Wild" is the closest I can find. ETA: I found this on starting roses from seeds: http://www.alaskarosesociety.org/documents/seed_germ2.htm
