Agastache 'Guava Lava' is a patented (US PP36,001) hybrid hyssop bred by Hans A. Hansen for Walters Gardens, from a cross of two proprietary, unreleased hybrid selections. A dense, well-branched, multi-stemmed perennial, it produces large coral-orange flowers held in showy mauve-pink calyxes from early summer through frost, with the ornamental pink calyxes remaining attractive even after the flowers fade. It thrives in full sun and lean, well-drained soil, and holds up well to summer heat.
