Romance ? If you're trying to woo someone or perhaps hoping to inject a bit of good old fashioned romance and spontaneity into your relationship or marriage flowers are still one of the most effective tools of seduction.

For something a bit different though there are plenty of attractive alternatives ? Lilies, Daisies, Orchids and Wildflowers for instance are all associated with conveying a message of love.

Congratulations ? Obviously you're looking to express something of the celebratory spirit here so consider going for bold, bright and contrasting colors that you feel really communicate a sense of fun and playfulness.
