The Arnold has a nice collection of fragrant Ghent hybrids labeled with the artificial species name R. gandavense.
Hunnewell Pinetum (1921) is the source for this 'Anneliesae.' Arnold Arboretum in Jamaica Plain Massachusetts is famous for its large collection of hardy woody plants. The arboretum is open to the public.
