Sort of. This M. parkinsonii is well on its way to having four heads, so the flowers look a bit random. This might be my largest plant grown from seed.

This one I don't even know how many growing points it has, but obviously more than one.

Beautiful little cactus, the flower crowns on the mammillarias are some of my favorites
