Narrative
Full name as recorded at the U.S. National Arboretum: Tsuga canadensis (white new growth). Old tree thought likely to be 'Albospica' (NA 14367); there were formerly multiple plants in the area this is now growing. This is probably the same plant that was recorded on old (1980s) Bed 60 inventories as Tsuga canadensis (white tip), without an accession number. New accession number and identity assigned out of an abundance of caution. White new growth is evident in summer (visible at accessioning, 7/21/2025).
