In my opinion (and that is worth just what you paid for it!) daylilies are more expensive in part because they are more distinctive. How many TB iris can you properly identify by sight alone (no id tag) in a strange garden? I'll bet not many. Granted, there are a lot of look alike daylilies, but the daylily has such a variety of forms, sizes & patterns that it boggles the mind! Luckily the daylily community (mostly) have embraced this diversity and continue working with both old & new plants. Whereas it seems the iris community tend to want more uniformity and tend to balk at anything different or weird. When I (a newcomer) asked about 'space age' iris at my first club meeting, I was treated like a leper! Then when I mentioned I liked the broken color iris too, they almost kicked me out! LOL!
