Sorry, I slightly hijacked....
I had an oriental "Skyscraper" from buggy that had four noses, neatly arranged in a square. They didn't seem ready to separate (I give them a little twist at a potential breaking point between noses) so I planted it as is. I got the expected four stems, then the following year it didn't come back. I just don't find it advantageous to have multiple stems on one plant (bulb) sharing the same basal plate.
I don't know if there is a scientific explanation for this or I just have bad luck. Could be bad luck considering my crummy clay soil.
