Narrative
Full name as recorded at U.S. National Arboretum: Juniperus horizontalis 'Douglasii'. Accessioned as an "old USNA plant" in 1975, without ID; a single plant, 4 feet in size at that time. A herbarium specimen was collected by Bob Doren under number RFD 1675. The plants in the garden have an old display label indicating that the cultivar is 'Douglasii', but this identification was not recorded elsewhere in the accession's record. The ID does seem plausible based on the plant's physical characteristics, but it is still somewhat uncertain. If they are 'Douglasii', then it is likely the plants belong to NA 4522. -SBL Form received: unknown propagule type.
