**Small world.
I did a search for the other colors of D. imperialis after they were 
discussed on the list and remembered that we have an antique rose 
nursery about 40 minutes away, and she carried two different D. 
imperialis, a deep purple with an orange center and a double white. 
Both, she said, came from Strybing. I picked up one of each today.
