Prefers climates with cool summer temperatures. Appreciates some part afternoon shade in hot summer climates. Plants often struggle in St. Louis summers, and are generally not recommended for growing in hot and humid summer climates south of USDA Zone 7.

After bloom, promptly cut back spent flower spikes to the basal foliage to encourage an additional late summer and/or fall bloom.
