Sunset magazine did a series of tests on extending vase life of
cut flowers. My recollection is that 1 part 7-up to 3 or 4 parts
water was the most effective of the homebrews... the citric acid
dropped the pH to reasonably low levels, and the sucrose provided some
carbohydrate. Aspirin and vinegar and copper pennies all were quite
ineffective for most species tested.
Looking at the indexes on the web site, I think the article was in
the August 1996 issue, pp. 51-52.
