Agastache 'Blue Boa' (Hyssop)

Agastache 'Blue Boa' PP24050, EU38274

Hyssop or hummingbird mint

Deep violet-blue flowers and wider flower spikes
Introduced by Terra Nova Nurseries

Luxurious, deep violet-blue flower spikes over ultra-green foliage. Unlike any other Agastache. The flower spikes are long, wide and extremely showy. It's a great perennial color spot for summer bloom. It is drought tolerant once established and attracts hummingbirds as well as butterflies. We have found all of that to be absolutely true in our trial gardens. This is a must-have feature in your perennial beds and meadows.
