Good luck with your program! Not to start a war on semantics because it can be a contentious subject, but if you're searching for cultivars in the AHS registration database or anything derived from it, the term "bearded" is not used because the AHS does not recognize it for daylilies. That's because it is an established botanical term that doesn't fit daylilies, at least not yet (basically it means having hairs). In the AHS they would be registered as cristate.
On another note, dormancy does not automatically convey hardiness, and evergreen does not necessarily imply tenderness. Also a daylily may behave differently in different climates as far as foliage habit is concerned. I have southern registered evergreens that set dormant buds in winter here in Zone 4, and emerge with the typical "spear" shoots. I also have evergreens that just do the mush thing, die back completely, and then continue growing where they left off come spring. They're all equally hardy and we don't always get much snow cover here (although we're getting some right now as I type this!). Where the plant was hybridized may convey more about its potential hardiness than foliage habit.
I briefly had 'Texas Feathered Fancy' but it did not make it through its first winter here, sadly. That doesn't necessarily mean it woudn't survive for someone else in a cold winter area but is just my experience.
