Looking lovely in the dryland garden now is the amazingly vigorous Agastache ‘Queen Nectarine’. This amazing giant measures 3.5′ tall x 3.5′ wide, and is adorned at any given time, May through October, with hundreds of flowers, perfectly designed for hummingbirds. Many of the non purple-flowered agastaches struggle in our hot, humid, rainy summers, but not this one. Hardiness zone 5a to 8b.
