HELP!! Does anyone know of a source for this plant? I need over 20 of them for a wildlife garden I am designing in Maryland for the Audubon Naturalist Society. Have not found it available anywhere. Have seen some beautiful examples at the National Garden in Washington, D.C. - all grown by the curator of the collection. Tried to take cuttings and propagate the plant last year, but it didn't work. Please e-mail: Jane Collins Thanks.
