I got these plants from my mother-in-law. The large one in the center grew from the original (which she gave me a while ago and is now dead), the smaller one to its left is its pup, and the plant on the right is a different variety that she just gave me (shown below also). The first two were separated several months ago; the last was just separated yesterday from its parent, along with two slightly smaller pups, none of which are in the photos. The larger plants were both grown exclusively indoors, and the smallest plant almost exclusively outdoors (until now).
I suspect that the larger two are Dwarf Cavendish and the smallest is Super Dwarf Cavendish. Does anyone care to confirm, or to correct me? And please pardon my messy room.
