42-54" tall x 24-30" wide (cutting propagated). Fill your garden with a big cloud of gorgeous, glowing lavender-purple flower spikes. 'Blue Blazes' is a large, vigorous hybrid that blooms non-stop from mid-summer into fall, attracting butterflies and hummingbirds with its nectar-rich flowers. While the plant takes two growing seasons to reach its full size, it blooms the first year from planting. Situate it in full sun with a well-drained soil. Pinching back the plant in late spring keeps it more compact. 'Blue Blazes' is an amazing hybrid between our own Agastache 'Desert Sunrise' (introduced in 2000) and the blue flowered eastern native Agastache foeniculatum.
