This pollinator magnet is a striking addition to the backyard meadow! Agastache ‘Blue Boa,’ more commonly known as Giant Hyssop, grows to about 3 ft tall featuring upright vertical spikes of vibrant violet-blue flowers. It begins to bloom in early summer and continues to bloom throughout the fall. Agastache ‘Blue Boa’ makes an excellent accent plant and is adored by bees, butterflies, hummingbirds and other pollinators. The leaves are fragrant and exude a pleasant licorice scent. Agastache is drought tolerant and hardy to zone 5. Deadheading spent flowers is recommended to promote additional blooms. Makes a great cut flower.
