Narrative
Cuttings obtained from a supposed original introduction (second distribution) of Clethra alnifolia 'Pinkspire', bred and selected from seedling lot NA 26887 by O. M. Freeman at the U.S. National Arboretum. From OP seed of NA 7779 (C. alnifolia 'Darlington', acquired from Coville and possibly from Elizabeth White of New Jersey) growing near another pinkish-flowered selection (possibly NA 7781); per Freeman letter no white-flowered clones were present on the grounds at that time. Seed produced in 1939 germinated in 1940, and one outstanding, non-fading pink clone was selected and named 'Pinkspire'. PI book record: "190213. Clethra alnifolia. From Washington, D.C. Cuttings obtained from the National Arboretum. Received August 16, 1950. Pinkspire." This introduction was never accessioned before, so NA 81114 will serve as the original NA accession of this USNA introduction. [IMPORTANT NOTE: Upon flowering, it was evident that this is not 'Pinkspire'; the flowers are entirely white with no trace of pink. Either the accession was mislabeled at the point of origin or it had somehow sported to an all-white version.
