This is a popular cross of Brassavola nodosa x Cattleya aclandiae. This was a seedling and it is it's first bloom. Having seen the diversity of these particular plants i had no idea what to expect but i'm very pleased with it. It changed quite a bit while it was opening. I wasn't around when it was opening but a friend took a picture and you can see what it now looks like fully open with green petals and sepals
