Agastache ‘Rosie Posie’

Giant Hyssop 'Rosie Posie'
Loved by Pollinators Fragrant Scent Hardiness H3

Agastache ‘Rosie Posie’ (PBR) brings waves of lavender-pink flowers from July until autumn, with dark purple calyxes that continue to lend colour even after the blooms fade. Its upright, clump-forming habit makes it a medium perennial that stands out in a mixed border. Fragrant stems and leafy growth add sensory appeal, while pollinators are drawn in abundance. Well suited to gravel and cottage-style planting, it performs beautifully in sunny Irish gardens.
