Agastache or hyssop is an old-fashioned perennial plant that's gaining in popularity with the introduction of new varieties. Agastache is a versatile plant. It has attractive foliage and flower spikes that bloom in a range of colors, such as white, blue, pink, and red. The plant generally grows 18 to 36 inches tall, depending on the variety, likes full sun, and is hardy in USDA zones 5 to 9.
Agastache rupestris 'Apache Sunset' is a relatively new addition to the Agastache line. It features smoky gray, finely cut leaves on a 20-inch-tall plant. 'Apache Sunset' has salmon-orange flowers that emerge in midsummer and last until frost.
Like other Agastaches, it has aromatic foliage, too. The leaves have been described as smelling like licorice, mint, or even root beer when crushed. Whatever the fragrance, 'Apache Sunset' is a brightly colored, easy-to-grow, long-blooming perennial for your border that butterflies and hummingbirds will love as well.
