Even though it’s commonly said that adding aspirin to the water of your roses will keep them healthy, there’s no scientific evidence at all. Wait a minute guys, aspirin is meant to be used by human beings, and as far as we know flowers are not human beings, as beautiful as they might be. They’re… flowers.
We’ve done our research — yes, we’re that professional. FloraHolland, a flower auction company, launched a study on the subject and carried out laboratory tests (parameters being as close as possible to those of an apartment). The findings were as follows: aspirin has no positive effect on the longevity of fresh cut flowers.
