Showy cross between Agastache rugosum and Agastache foeniculum that blooms from mid-summer to frost. The smoky violet-blue flowers and dark purple buds (calyxes) are held on long spikes over nice mid-green foliage.  Agastache hybrids are typically winter hardy to at least USDA Zone 6. Where winter survival is a potential problem, plants should be sited in protected locations (e.g., southern exposures) with leaf and flower stems being left in place over winter for additional protection.
