The mid-blue flower spikes of this hybrid anise hyssop continue for many weeks in summer, to the delight of bees and butterflies. It offers the pollination-pleasing flowers of the native Agastache foeniculum but in a somewhat more compact size, thanks to hybridization with the East Asian native Agastache rugosa. Excellent for hellstrips and other sunny dry garden niches.
