Positive RobertWM On Jun 14, 2009, RobertWM from Clawson, MI wrote:

A little bit slow for me but incredibly beautiful. Large, tall, deeply ruffled and luscious color..The undersides of the falls are light yellow as are the buds, but it opens a rich ivory layered gold at the hafts. The flower looks delicate but the petals have very heavy substance, almost like leather' and in the coolish spring we've had in Michigan this year, they're lasting a good five days.The hybridizer, whose other work I'm not familiar with, can be very proud of this one.
