These footnotes to the amaryllis series provides some additional anecdotal information to round out the experiment …

Amaryllis leaves fall over

Why bother with alcohol? Because amaryllis grown indoors, especially in water, often grow tall and fall over. Here the leaves of the water fed bulb fall down and had to be tied back up. At various times in the time lapse movie seen in an earlier post you’ll notice that the water fed bulb was rearranged to stand upright.

UPDATE 10/23/2009: I’ll be repeating the experiment with a slightly more diluted alcohol to see how much bigger I can grow the bulbs before they fall over! Watch for updates in November and December of 2009 in a follow up post: Amaryllis on Alcohol: Revisited …

This frame grab pretty much sums up the experiment’s results: The alcohol fed bulb on the left is shorter and has smaller blooms compared with the water fed bulb on the right. Blooms from each bulb lasted equally long.

I’ve been growing a pair of amaryllis bulbs as an experiment. One bulb has been drinking water, as it aught to. The other has been taking a tipple of vodka.

The hypothesis is that the height of alcohol fed amaryllis bulbs will be shorter — but that the blooms will be of equal size and last as long as water fed bulbs.

I’ll be wrapping up that experiment and posting the results — which includes time lapse video and a growth chart/graph. Links to the research on paperwhite narcissis that prompted me to do this experiment follow below the photographs.

UPDATE: I have a new experiment going in 2009 using lower dilutions of isopropyl alcohol to optimise growth without going leggy on the foliage. Amaryllis on Alcohol: Revisited.

amaryllis alcohol vs water

ABOVE: These are the amaryllis I’m growing at the office which feature in the time lapse movie you’ll see in an upcoming post.

amaryllis in alcohol

ABOVE: This short little fellow was fed a 7:1 water:alcohol mix from day one and remained alarmingly short, so when the flower head was near fully formed, but not opening, we switched back to 100% water and were rewarded with this diminutive display.
