Last year I planted several varieties of Agastache in my little garden and I really like the plants and so do my Hummingbirds and my Butterflies. Several species of these wonderful herbs are native to the southwestern Regions of the US and the northern part of Mexico, some species are found in Europe and Asia. Agastache blooms in summer and most have aromatic foliage that can be used in teas. The flowers come in an array of colors, blue, red, pink, purple and even bright orange. Most varieties take moderate watering, but for the plant to look its best and to keep it blooming, a little more water in a dry spell is needed. If deadheaded the plants will rebloom and some will self-seed freely. The flowers are tubular and nectar rich. Species from the Southwest and Mexico are more drought tolerant and need very good drainage and like a gravel mulch to keep their crowns dry, a bark or compost mulch is too rich and too moist and can make the crowns rot. The most commonly grown and available plant is Agastache Cana - Texas Hummingbird Mint. Plants are to 3 feet tall and have raspberry-red flowers. A. barberi is a native to Arizona and New Mexico, grows 2 feet tall and wide and has pink-purple flowers. A. foeniculum, a specie from Central America growth to 3 feet tall with lilac-blue flowers and foliage that is anise-licorice scented, also called Anise Hyssop. A.mexicana can grow to 5 feet tall and has pink flowers, also called Giant Lemon Hyssop because of its lemon scented leaves that can be used in teas. Another native to Southern Arizona is A.ruperis - Licorice or Sunset Hyssop. This plant has fragrant and gray-green leaves and orange flowers. The last plant you will find in my garden is A. rugosa - Korean Hummingbird Mint, from Asia, flowers are purple blue. All these plant look good interplanted with Penstemons and Lavender and if your soil can support Lavender and Penstemons, you can grow Agastache.
