Ben Berliner did a lot of hybridizing with promenaeas and this was one of his second generation hybrids. This is a cross of Promenaea stapelioides with Promenaea Limelight (ovatiloba x stapelioides). He had given me a flask and this is the 2nd best of the seedlings. I wasn't aware it was in bloom until I moved it when I was trying to find another plant. Nice surprise.
