xmas cactus from Chinese restaurant in Pueblo CO

Besides being pretty, this plant has a secondary virtue. It blooms twice a year, once just before xmas and again 3 months later.

My current theory is that the bigger flowers make abscissic acid which causes abscission of the small buds, along with the spent big flowers.   (23/32)
