Wow - do Schombs and Sophs cross? That's like trying to mate a mouse and an elephant. Will you cross in both directions, Aaron?
I can see progeny from one direction: the diminutive plant will have a 5" flower that will pull the pot over into a face plant.
In the other direction, you'll have a towering flower spike ten feet tall, but a step ladder will be required so you can view the bloom with a magnifying glass!
