Flowers make people happy: Flowers have an immediate impact on happiness. All participants in a research study expressed "true" or "excited" smiles upon receiving flowers, demonstrating extraordinary delight and gratitude. This reaction was universal, occurring in all age groups.

Meanings of rose colors: In Victorian times flowers had assigned meanings, but even then there was much discrepancy. Today there are so many flowers and colors that this tradition no longer applies. Red roses are traditionally associated with romantic love, but this is not a universal rule by any means.
