Hens & Chicks, known botanically as Sempervivum (which means "lives forever" in Latin) are truly amazing plants. Though they look exotic, they easily survive outdoors in areas as cold as USDA zone 3. They create carpets of colorful, textural rosettes that are irresistible to the eye and to the touch, and they're utterly unbothered by pests. In fact, the only thing that does bother these unique hardy succulents is water: they barely need any! Plant them in your sunniest, driest spot and enjoy the show for years to come.
