Agastaches are scented perennials from North America, China and Japan, where they grow in poor, dry ground. They're perfect for growing in gravel or Mediterranean-style gardens, and may also be grown in containers on a sunny patio.
Agastache 'Blue Boa' is a borderline hardy variety with vivid purple spires that are packed with flowers. It forms an upright clump of fragrant foliage, and will flower from June until the first frosts in autumn. A brilliant plant for bees.
For best results, grow Agastache 'Blue Boa' in full sun, in well-drained soil. Let the old flower spires remain over winter to provide interest. In colder regions, protect from frost in winter. Find out more in our Agastache grow guides.
