Agastache are equally good in the border, and as a candidate for container growing. The better the drainage the happier the plant. Scented foliage is good for flavoring drinks and drying. A customer advises us that her Goldfinches are wild for Agastache seed.
Good drainage is a must! Agastache thrive in full sun and rarely need divided. Most will self sow to spread, so deadhead by removing faded flowers to prevent seeding. Leave stems to overwinter; tip or remove new growth in early to mid spring for more flowering stems and a more compact plant. To promote strong stems avoid too much water and fertilize only once a year in fall.
