First bloom seedling I got a few years ago from Paph Paradise. Cross is ‘Dark dark’ x ‘Big-n-flat’. I thought this was a casualty of treating my plants for thrips this summer, since the entire sheath turned brown, but I guess it really wanted to bloom!
Thanks for the comments! The flower has settled in some more, and while it exhibits some ruffling along the edges, overall it has really flattened out.
