The registered name of the hybrid you had is Phal. Luedde-violacea. You may be able to still find it around. Other than that, any hybrid with violacea is likely to be fragrant. Lueddemanniana is also fragrant. I have the ochracea form in bloom right now and it has the most wonderful jasmine-like fragrance. If you like smaller flowers, Phal. Equalacea (equestris X violacea) is often fragrant. I have one that has a rose-like fragrance and blooms constantly thanks to the equestris influence.
