24" x 15" wide (seed propagated) Originally collected in Korea by Heronswood Nursery owner Dan Hinkley, this beauty is proving itself to be an excellent performer in the U.S. The deep violet-blue flowers keep coming all summer when kept deadheaded to prevent seed set. The foliage is a deep, glossy green with a hint of purple to the undersides. The entire plant is intensely mint scented! Unlike the southwestern _Agastaches_, Korean Hyssop will do well outside of the western U.S. in the wetter winter climates of the Midwest and East. Zones 5-9. Interested in Hummingbirds?
