The first is one of my most reliable bloomers, Sunset Glow 4n. It is EYOF via Chuck Acker. The second is Fritz Schomburg, besseae "Crystelle" x Pk. It is a strong grower and the flower remains flat. The third is Peruflora's Cirila Alca. I bloomed three this year and this was the best of the bunch. It is not flat but it has a smooth 30 degree twist through the petals, so it doesn't look too bad.
