Reflections on Narcissus
turns out they like a stiff drink
Paperwhite narcissus (Narcissus tazetta) are lovely bulbs to "force" for the holidays – they have clusters of intensely fragrant, charming white flowers and, since they don’t require cold treatment and can be "planted" in a jar of water, they’re about the easiest bulbs to start indoors.
If you’ve grown paperwhites before, you know the leaves and flowers tend to grow very long and floppy; sometimes they need to be staked, tied or otherwise bound up. Most of us, unless we’re aspiring understudies of Martha Stewart, just lean them against a wall or just turn the other way as the flowers droop down onto the table.
But there’s a solution – literally.
A study conducted at Cornell University in November 2009 showed that adding a solution of 4-6 % alcohol to the water keeps the stems stout and the flowers upright.

Or, for quickie instructions without the explanation, skip that and just read this, directly from the study’s recommendations:
“Start your bulbs in plain water. When roots have formed and the green shoot is 1 to 2 inches long, pour off the water and replace with a solution of 4 to 6 percent alcohol. If you are using 80 proof liquor (40 percent alcohol), that works out to one part gin (or the like) to 7 parts water.
“Rubbing alcohol (either 70 or 100 percent isopropyl alcohol) can be substituted; just remember to dilute it more. Keep the beer and wine for yourself; their sugars damage plants.”
Note: I wrote in the original post that paperwhites take 4-6 weeks from planting to flower. But reading through my notes over the years, I see they usually flower in 3.5 to 4 weeks – rarely 5 or more. Bright light and steady water obviously help and they seem to produce flowers more quickly when planted in water than they do planted in pots with potting soil.
