All varieties are aromatic and highly attractive to pollinators, including hummingbirds. Pick the leaves as desired for fresh use in the kitchen. For drying, harvest leaves before the flowers open.

Sow indoors 6-8 weeks before the last frost, or direct sow in early spring when a light frost is still possible. Seeds can also be direct sown in the fall, as the first frost approaches. Optimal soil temperature for germination: 15-21°C (60-70°F). Seeds should sprout in 10-40 days. Bottom heat will speed germination.
Barely cover the tiny seeds with soil. Thin or space transplants 45-60cm (18-24″) apart. These vigorous perennials will grow in, closer together over time.
Any ordinary garden soil will work. Plant in full sun to partial shade. Where summers are long, plants are prone to mildew, so avoid overhead watering. Deadhead regularly to prolong the blooming period. These perennial plants spread by rhizome growth, and should be dug and divided every three years.
