"Viagra makes flowers stand up straight"

I was reading up on the challenges/prices of changing starch from non-edible plants into usable biofuel (hey, it's an interesting engineering question, okay?) and thanks to the nature of Hypertext I eventually stumbled across a précis concerning Viagra/plant erection:

"Viagra (sildenafil citrate) is good not only for treating male impotence. Israeli and Australian researchers have discovered that small concentrations of the drug dissolved in a vase of water can also double the shelf life of cut flowers, making them stand up straight for as long as a week beyond their natural life span. "

"In this latest research they found that 1 mg of the drug (compared with 50 mg in one pill taken by impotent men) in a solution was enough to prevent two vases of cut flowers from wilting for as much as a week longer than might be expected."
[Emphasis mine.]

Goes in the "Well, Why The Hell Not" folder....
