These are wild rose hips, the seed bearing fruit of our local wild roses. They provide one of the richest plant sources of vitamin C. Rose hips contain the carotenoids beta-carotene, lutein, zeaxanthin and lycopene. I wouldn’t recommend eating them straight from the bush but mixed with sugar or other flavors they are common in teas, jams, jellies, marmalades and such. I understand that rose hip soup, “nyponsoppa”, is popular in Sweden. It is also made into wine and brandy in some countries.
