I would call this orange hyssop, but this plant is generally sold as orange hummingbird mint (you can guess which name would likely sell more plants). It’s native to Mexico, but grows on mountains, so it performs well as a perennial in more temperate climes. Like most members of the genus Agastache, its foliage is aromatic when crushed, but I wasn’t able to identify a related scent to be able to describe it to you. I’ve read “anise” and “licorice” used to identify the scent, but that wasn’t my experience.
