Physostegia, otherwise known as the obedient flower, is a hardy herbaceous perennial that will do well in damp sunny spots. The common name is derived from the fact that the individual flowers can be pushed with your finger, to face in almost any direction. A flower on a hinge that amuses little children and some gardeners.
New shoots grow annually from the rootstock and little summer care is required. In early autumn, cut the stems down completely to ground level and tidy the area. During the winter months, long established clumps may require lifting with a fork, the rootstock divided, and the best clumps returned to the same spot after cultivating the area. An application of fertilizer or manure in early spring will ensure the plants get away to a good start. Taller varieties may require staking, but most will remain neat and tidy.
