Growing directions
Surface-sow seeds and keep barely moist; germination is slow and uneven, so starting from cuttings or divisions is often more reliable. Plant in fast-draining, lean soil — rich or wet conditions promote rot and weak growth. Prune plants back by about one-third after the first flush of blooms to keep growth compact and encourage a second flowering. Harvest flower spikes just as the buds begin to open, bundling and hanging upside down in a warm, airy space to dry for sachets, culinary use, and aromatherapy.
