Hard to say. I have an Emmerich, Filled to Overflowing, that does the same for me. It started out as 2 very nice fans and they have dwindled down. I only have one fan now and it bloomed much later this year than it normally does. I also thought that hers would be very hardy in my zone. I have had others do that too. Seagull's Heaven is barely hanging on. It did well for 2 years and this year it looks like a miniature, very small fans and super tiny. Mine have also been fertilized and have had lots of good rain water. I purchased Dragonfly Dawn this past spring and I am wondering if that one will do the same thing, if it even makes it through my winter here.
