I prefer dog rose (Rosa canina) which makes an excellent hedge plant, good forage plant - harvest red hips before they wrinkle but after frost - or pick when red and put in freezer for 24 hours. amazingly the hips are richer in vitamin C than oranges. Also Rosa rugosa (actually Japanese) produces big hips though not so flavoursome. Most species roses will also produce usable hips i.e. avoid ones that are grafted onto a stock plant. However I would add that all parts are edible, so you can use the leaf as tea and rose petals in salads. There is a lot more detailed info on ways to use at https://www.eatweeds.co.uk/rosehip-faq
