This cross from Sam Tsui is truly amazing because not one flower looks the same. They are all the same cross but the flowers tend to come in many shapes and sizes with the notable feature being their wings. 
Come and grab yourself one in a 3.5" pot and see for yourself!
 
Please note that this is a Seedling Population, not a Mericlone, which produces identical copies. The image provided is for illustrative purposes only. Each plant from this cross will be unique, with flowers varying in characteristics inherited from both parent plants.
