I love older daylilies, especially those that were ahead of their time (many of them looking quite close to the most sought-after new intros). But, I seem to find that most of my older ones increase at a dramatic rate, and I don't want to propagate seedlings that will also require constant digging and reducing to keep tidy at the mature stage. Anyone have older cultivar experience with amazing colors or patterns that increase more slowly, replacing older fans and expanding perhaps a bit, but not at crop-stock rates?
