Instead of fantasy landscapes forced into bloom, a trade show has the energy of an international marketplace, where growers discuss the fine points of their new favorites — plants like Citronelle, a lime-green heuchera that can stand up to heat and humidity; or new hibiscuses like Plum Crazy and Copper King, which tolerate dry soil and are hardy to 30 below zero; or the rarest of plants, like a bonsai metasequoia, also known as dawn redwood, which grows only three inches a year, making it perfect for a pot on your patio.
