This sport of H.
'August Moon' was registered by
Randy Goodwin of Indiana in 1990. It forms a large size (20 inches high) mound of foliage whose
colors intensify as the season progresses. The plant bears pale
lavender flowers in late July.
suspect that this plant is named in honor of Mr. Bobby "Bob" Knight,
former basketball coach at Indiana University (and later, Texas
Tech). Just my guess.
