I purchased Last Snow Flake in the winter of 2010 for spring delivery that year. I bought it on the Lily Auction from Northern Lights Daylilies. It was purchased as a single fan and that was exactly what I received.
As of 2015 I have 6 or 7 fans. So I have would say I have had moderate increase. Not what I would describe as a robust or vigorous plant. But it does okay. It is the very last plant to break thru in the spring. I now know to expect that and not worry about it. I have moved it to a bit safer spot where it is not likely to get stepped on and I put a tomato cage to mark where it is at during the winter.
Mine does not come close to being 32 inches tall. It is described as a very late but here in my garden it is among the early bloomers. Blooming here at the end of June.
Mine tends to show lots of green on it and love that!
