Very hardy! 32" tall, space 16" apart, Zones 5-9, full sun, 3" pot. Save 15% on three or more plants!
Deep, violet-blue blooms all summer. The flower spikes -- wider than other Agastaches -- tower over ultra-green foliage. Much bluer flowers than the old gray-tinted 'Blue Fortune'. Hybrid of American native plant. Plant patent applied for. "The Agastache Blue Boa I purchased from you is blooming like crazy. It is stunning, and the bees love it!" – CS in DC
