I received Aslan as a bonus plant in the Fall of 2013 I believe. It bloomed the first year (2014) and while it wasn't one I would have picked I thought it was rather nice. However, it did not bloom in 2015. I have had several colder than normal winters since acquiring it so I'm hoping it's just adjusting to the climate.
Update: Aslan eventually died. It could not handle the cold, rarely snowy winters and the wild temperature swings in the early spring. I would not recommend it for northern growers unless they had fairly continuous snow cover in the winter and gradually warming springs.
