The question was raised earlier about fragrance in hemerocallis which prompted me to realize that of all my many types, none are fragrant. Further thinking about older midwest hybridizers, Hall, Fay, Griesbach, Marsh, reminded me that of those people , none had selected for fragrance as far as I know. They concentrated on tetraploidy, bud count (up to 30 +), sturdiness (tolerance for 30 mph prevailing prairie winds), colorfast reds (little success), and breeding for white. Current hybridizing is of a different order, exemplified by Moldovan and others whom I don't know. http://www.daylilytrader.com/ is instructive here --as are the prices which are at times astronomical. A good place to start for information and for browsing is Eclectic Gardens which has an imnpressive array of varieties arranged alphabetically and with classificatory information on each as to ploidy, height, season, reblooming capability, evergreen or winter dormant--and very good color pictures They do not offer the diploid species flava or its synonym: lilioasphodelus.
