Another remarkable release from the U.S. National Arboretum's shrub breeding program in McMinnville, Tenn. in 2013 for which they should be rightly proud. Blooming a week later than other sections and holding its mature inflorescences even longer it really extends the season. The inflorescences are 9 inches long and age to pink while the plant grows to 6 ft. tall by 9 ft. wide.
