Dwarf Pomegranates, Punica granata nana, are hardy here (USDA Zone 7); most people don't realize it so there aren't a lot around but they're kind of fun. Dark green leaves and orange flowers in the middle of the summer make them identifiable from at least 100 feet while driving. I found buds, opening buds, and partly and fully open flowers on one lant in the Herb Garden. I didn't find any fruit because they don't set a lot of fruit. There's usually one around by the end of the season on three or four plants. Still, there's something about Pomegranates; they're symbols of fertility, fecundity, harvest; you just want one in your garden.
