Oh my, sorry to hear that, they seem to be doing well here. They are about 2 feet wide, and about a foot tall already. 6 of them have little buds coming that are about an inch and a half wide already. I think they like the cooler weather. The last time I grew them we had that really hot and dry summer. I watered them every day and they did OK, but this year they are growing like mad. Last time I had one plant that got some kind of black fungal type of thing going on. It didn't die, but it didn't produce either. I'm thinking about letting some blooms open to make seeds. Do you think they will come true from seeds or are they hybrids? They are Imperial Star.
