This beautiful Agastache is a xeric plant that likes a lean, well drained soil along with lots of summer heat. The natural range is from southeastern New Mexico to central and south-central Arizona and into northern Chihuahua, Mexico.

One of my favorite Agastaches! The leaves have a wonderful scent, the color of the flowers and the leaves are beautiful and the combination of the two is stunning! Over the years, I've planted it into the ground and into containers around my yard. I love it!

For most of the summer, Agastache ruprestris is covered in brilliantly-colored flowers that attract hummingbirds, butterflies and bees. And Sunset hyssop fills the air with a great aroma similar to root beer or licorice.

You can use sunset hyssop leaves to make tea.

"Threadleaf giant hyssop (Agastache rupestris), also known as Licorice Mint, is a wildflower of the mint family (Agastache) native to the mountains of Arizona, New Mexico, and Chihuahua, Mexico. Popular in xeriscaping because of its heat tolerance and ability to thrive in dry, nutrient-poor soil, it is often planted in a containers or as a border flower and used to attract hummingbirds. Displaying gray-green stems and leaves while dormant, its orange flowers with purple buds bloom forth from mid-summer until the fall; if crushed the petals exude a pleasant scent."
