This perennial is slow to germinate, so sow indoors in seed trays, using bottom heat (18 degrees C). Keep soil moist until the seedlings are well established. Cuttings can be taken from the tips of shoots. Place in sandy soil and keep moist.
Enjoys full sun and warmth. Transplant once the root system is well established. Very attractive planted in groups. Pick the flower stalks before the last flower on the spike has opened. Harvest on a dry day before the sun is too hot. Hang in bundles upside down in a shady, airy place. Store whole spikes or remove the flowers from the stems. Store in airtight containers.
