Yes I have another hybrid or prup. burkii x. leuco that grows like yours except you cannot see the areoles except when it opens because it turns dark red (Like my purp. burkii's in the picture). I don't know about that plant yet. I have not had this plant for very long so I'm not sure yet. For my info (FMI) what hybrid with purp. has round petals. (rubra maybe)? and dark red flowers/maroon flowers
