Hardy only into the teens, so it is best overwintered in a protected area in the Washington area. It starts flowering in early summer and blooms until the first frost. It is a wonderful hummingbird plant with large yellow flowers that hang downward like a bell. It is relaively easy to propogate from softwood cuttings taken in the spring.
