Agastache is an easy to grow perennial herb. Agastache has all of the qualities I look for in a perennial: low maintenance, drought tolerant and loved by butterflies, hummingbirds and pollinaters like the bumble bee. It's especially pretty to see the orange sulfur butterfly feeding on the purple flowers.
A prolific bloomer: agastache's tubular, spikey flower heads bloom from July to September. Height is between 1' to 3'.
