Patricia Davidson, Darling Downs. Another group I’ve had success with are the Reithmuller roses. Reithmuller was from Toowoomba and a relative of his here is trying to get people on the Downs interested. From cuttings I’ve grown the following. Large trusses of small very double flowers: ...and Spring Song, both pink. The above roses all have Gartendirektor Otto Linne somewhere in their breeding and have the same leaf formation and long arching canes.
