Agastache 'Blue Boa'
The longest-blooming agastache that we’ve come across – the deep violet flowers are abundant for at least five months of the year. A very versatile perennial companion that works well with a huge range of Diggers perennials.
How to grow
Plant in full sun in a well drained soil. Dry-tolerant once established, though will benefit from supplementary watering during extended dry periods. Regularly deadhead to prolong flowering and prune back to a low mound in early spring.
