Ted Petit (now Greg Goff) is doing that type of line, resistant landscaping daylilies. He's had them out for awhile and you can find them in the AHS database (or here); they were actually out before they were registered. They are being sold in "big box" stores but not sure what areas and being marketed for landscaping. He wanted to come up with small, compact, landscaping daylilies that were resistant to rust.
