Once in a while we come across new plants that quite literally take our breath away. During the dog days of summer, the robust Agastache 'Blue Fortune' is a mass of soft powder-blue flower spikes from July onwards, making it a magnet for butterflies and admiring visitors alike.

Its cousin, Agastache 'Firebird', produces a profusion of long-lasting blooms that range from a coppery-orange to a glowing coral-pink. Careful breeding and selection gives both these newcomers a remarkable resilience to our cold, wet New England winters as well as a show of glorious color, exceptional garden performance, and a long season of bloom.

In full sun and well-drained soil, these star performers thrive, happily shrugging off both summer heat and early frosts.
