My Chinese four o’clocks came from seed a Chinese exchange student sent me about fifteen years ago. They are totally satisfactory. Neither gophers, nor deer, nor ground squirrels, nor any other pest seems to like them while hummingbirds think they have died and gone to heaven when the flowers are in bloom. The flowers even bloom on Chinese time. While other four o’clocks are supposed to open at around four in the afternoon and bloom all night, these plants open their flowers the first thing in the morning and keep them open until about four in the afternoon.
