This article needs to be written. Can you do it? Will you? Let us know! Some things look edible, but how can you be sure? The mountain ash (or rowan) berries on the left, for example have too much acid and will give you a stomach ache if you don't boil them first. Rose hips are edible, though if they're not this big and juicy, they may taste rather sour. Also, they're quite fibery, so chew them for a while, then spit out the seeds somewhere you'd like to find rose hips in the future!
