Agastache 'Astello Indigo', is a brilliant agastache that received the 2012 Fleuroselect Gold Medal for its outstanding garden performance.  The lighter blue flowers burst out of indigo flowering bracts for a unique color contrast.  Tall columnar blooming spikes are borne on top of strong square stems for a long period in summer.  Foliage is a rich green, slightly serrate, and deliciously licorice scented.  There is no browning to the bracts so even after the flowers fade the blooming columns still look attractive.  Our favorite blue!  A favorite of butterflies and other pollinators.
