Agastache ‘Blue Boa’

Agastache

Lovers of heat, these tough and drought-resistant Mint family relatives guarantee terminal spikes adorned with brightly colored, tubular flowers just about all summer long. Agastaches are easily grown in well-drained soil, and will bloom more profusely, over an even longer period of time, if the flowering stems are cut back midseason.

<i>Agastache</i> ‘Blue Boa’

A winner at the Colorado State Perennial Trials, this vigorous new Agastache sports an upright, well-branched clumping habit shaped by stiff durable stems and large, fragrant serrated green leaves. A beacon for pollinators and superb in cut arrangements, vibrant deep violet-blue flowers crowd spectacular 5 in. tall terminal spikes for months. ‘Blue Boa’ appreciates well-drained soil, wards off deer and tolerates cold weather best when its stems are left standing. (pp#24,050)

Blooms June–September

Size: 2' 0" – 3' 0" high x 14" – 18" wide.
