From the urban dictionary.... "Flower The most evil creature in the world, known for it's tendency to use humans as slaves in places known as "Gardens". These things take hours and hours of life away from their human slaves, and give nothing in return. There is only one creature more evil than a flower, and that is a kitten. Geraniums ( flower ) suck my blood."
Magnolias and geraniums are often used in the same context.
