I am wanting to establish a Spanish/Latin style garden and am looking for fragrant Oleanders. I have asked the local nursery to order me in a Mrs. Roeding which is apparently the most fragrant type. Is this true? What other types are fragrant? I have seen Madoni Grandiflorum, Proff. Martin Sunshine and Splendens Double Pink. Are these scented? I have read that splendens double pink smells of sweet talcum. True?
