Negative Mainer On Jan 25, 2009, Mainer from Durham, ME (Zone 3a) wrote:

Hardy enough in my zone but it blotches and melts in the sun. Gave it away to someone who wanted to try it. I prefer Vintage Bordeux or Strutters Ball for a purple day lily so far. They do not blotch and melt point seems to be much higher temps than Royal Occasion.
