On size of fans- I have been digging orders this week, and the fan size can vary so much between varieties. My garden is out in the middle of an open field- FULL sun, no wind protection, and the soil is pretty consistent throughout. I dug PERSIFLAGE yesterday (a Lambert diploid). It was lined out fall of 2008 and was 5 fans, so it wasn't a crowded clump. The fans were HUGE- like a Florida, raised bed, drip irrigated, highly fertilized tetraploid! Yet, there are some tets that right now have very slender fans. Within a few weeks that may all change. It depends on where they are at in their growth cycle. Sometimes I can dig a plant and it will be heavier than the same plant will be a few weeks later. Some plants make short fat tuberous roots, some have long fiberous roots, and some have both. You just never know until you dig it. I will say that I think WIND FRILLS has the longest roots of any daylily I grow. It is hard to dig because the roots are so long.
