Anise Hyssop
Blue Boa Agastache is a hardy, drought-tolerant flowering perennial that thrives in full sun and delivers season-long color with minimal fuss. Growing 24 to 36 inches tall and spreading 18 to 24 inches wide, this cultivar produces showy blooms throughout summer (June, July, and August) that attract pollinators while resisting deer browsing. Hardy in zone 5, it's a low-water plant that settles into established gardens with ease once initial establishment watering is complete.

Blue Boa lives up to its low-maintenance promise once established. The true appeal lies in its drought tolerance and pollinator magnetism, combined with genuine toughness in cold climates and complete indifference to deer pressure. Spacing at just one inch apart allows dense plantings in smaller gardens, making it surprisingly efficient for such a substantial plant.
As an ornamental flowering perennial, Blue Boa Agastache serves as a reliable mid-to-back border plant in summer gardens and pollinator beds. Its extended bloom window and low maintenance profile make it well-suited for naturalistic plantings and xeriscape designs where water conservation matters.
