Sow indoors in late winter, before the last frost date. Transplant once night time temperatures are steadily above 10°C (50°F). Otherwise, direct sow in autumn. Optimal soil temperature: 12°C (55°F).
Just cover the seeds, and keep moist in a sterile seed starting mix. When no risk of frost is left, transplant outdoors to containers or at 30cm (12″) spacing in the garden.
Provide some balanced organic fertilizer annually in the spring. Grow in well drained, fairly rich soil in full sun. Agastache can tolerate light shade, but will not perform as well. Maintain vigorous plants by dividing in the fall. Plants grown from seed may take two years to bloom.
