I found this photo on a Flickr gallery and I have no idea what this plant is. Is it supposedly a type of berry or something?
Without knowing the geography of where the photo was taken, we could guess this is a European Mountain Ash (Sorbus aucuparia) which is fairly widespread in North America and Europe (but doesn't really grow in South America, Asia, Africa, Australia)..
You can look up this plant for information on the berries. They contain vitamin C, but don't have much other desirable properties.
