How to Stunt Paperwhites with a Nip of Booze

A problem with paperwhites, as with many bulbs planted in pots, is that they grow quite tall and all of their weight is at the top. Researchers in the Flowerbulb Research Program at Cornell University have come up with an unusual solution to this top heavy problem: Alcohol.

When paperwhite bulbs are grown in a dilute solution of alcohol, the plants reach a height of 1/3 to ½ their normally expected growth - but the flowers remain normal size and last just as long. Why they thought of giving their paperwhites a nip, I don’t know. But it appears that the resulting water stress on the plants is just enough to stunt their growth, but not interfere otherwise.
