From what i have read, the Rosa Rugosa rose is the best one for harvesting rose hips. It is almost a wild rose, with blossoms that are not quite as single as the reglar wild roses; but not as full as a tea rose, either. The rosa rugosa will get about 4-5 feet tall, and spreads; so it makes a great rose hedge. I had some growing here; but we apparantly lost it one year; so I need to order a few more plants and then let them spread. You can actually save the rose hips from just about any rose, and I used to gather them from the wild roses when we lived in idaho; but the rosa rugosa is suposed to have the most vitamin C, and it has very large rosehips.
I should have planted that in my yard, might look into that. I'll have to read up on it and how I'd does here. Although I put that name in my search, this is what's coming up for my area and unless it's called something else I m not seeing it. I know little about roses except that is one thing I can't kill in Fresno...I don't have a green thumb. http://www.rainforest2548.org/sjvroses.html
".......taking D and C." Always been leery of those "D & C"s, after reading about it in a Frank G. Slaughter novel as a teenager! Frank
