Agastache, Arizona Sunset

Arizona Sunset is a pollinator magnet, bringing in butterflies and bees as well as the hummingbirds that give this perennial its common name. They begin as soon as the first flowers open in midsummer—softly colored, tubular, and boasting lavender shades with pops of peach. If they're this eye-catching to humans, imagine what the winged crowd thinks.

The blooms last into fall in most climates, and it's hard to mourn them when they pass, because the foliage has a strong, evocative licorice-mint scent that's just heavenly on a warm summer day. Brush past Arizona Sunset and you will be rewarded with fragrance.
