It is not a true cherry because it does not come from the genus Prunus. - The "bean" is a seed, usually two per fruit. It is not a true bean because it does not come from the legume family. Peaberry: - A peaberry is a coffee fruit that contains only one seed instead of two. - Roughly 5 to 10 percent of fruits are peaberries.
