Wispy Rays is a beautiful flower, when it blooms beautifully. The problem is that it is a true EVR which means that when we have a mild Winter here---it does great! However, when the Winter is bad---especially COLD, it does not do well. It has survived over the ten or more years I have had it here, but it has performed well only three times that I can recall. It may also be an erratic performer because Yes, it does get rust easily---and the rust really saps it's strength. I still keep it, but I'm not sure why.
