I found just about all the varieties there are on a Dutch site, not the best photo of Double Pleasure but the shape looks to fit and the Alberta trials should have a true photo.

I got my Coral Reef from T&M years ago, they are all similar to each other and said to come quite true from seed and mine looks like all the others I see, that isn't listed on the Dutch site I guess because it isn't from cultivated plant material.
It looks like either Double Pleasure or Pink Ruffles but as you see, the latter is normally very well cut and ruffled.
