Split cup ‘Edinburgh’

To all, I went to a bulb show at Smith College in Northampton Mass today and saw a pot of a 11aW-P I had never seen before named ‘Edinburgh’. Most interesting was that one of the scapes had two flowers on it, and I started to wonder if this was at all a common trait of this flower. Anyone grow it?
