Interpretive Summary: This article discusses current knowledge about the Glenn Dale azaleas which were planted on the south face of Mt. Hamilton between 1946 and 1947. The curator, her volunteers and staff have found over 100 Bell-numbered labels on Mt. Hamilton since 1991, revealing new facts about the azaleas planted at the National Arboretum. The National Arboretum azalea collection serves as a reference collection of documented new and old varieties and cultivars of azaleas. If a cultivar is lost in the trade, it may still be growing at the USNA. Propagators can acquire cuttings for reintroducing to the trade.

Technical Abstract: National Arboretum curator discusses labels found in past 25 years on Mt. Hamilton which reveal more information about the Glenn Dale azaleas planted there. The National Arboretum is a national reference collection of azaleas for older varieties that may be lost in the trade.
