Himalayan Bush Mint.  Surprisingly hardy species - the gestalt at first glance is gotta be tender - that will be valuable late summer-fall color.  Soft felty leaves on a plant that can hit ten feet tall, you grow this not for the aromatic and pettable foliage but for the tubular orange-red flowers in September-October mainly.  Cut to the ground by hard frost but will regrow and would totally groove on a wall in its colder zones.  Pronounced ko-hoo-nia.
