Rosehips
Rosa canina

If you leave the flower on your rosebush, the petals will fall off after it finishes blooming, and a small red fruit will form -- that is the rosehip. Rosehips form on any sort of rose shrub, even a hybrid tea or floribunda, but the hips most commonly used in foods and beverages are harvested from wild roses. Fresh rosehips are a source of vitamin C, which is how they got the reputation for being healthful.
