Flower a symbol of expression

In the modern world, we interact with groups of people, we go out on dates to see if we have 'chemistry', and finally, we spend a lot of time and effort trying to win over the object of our affection. Valentine's Day is a celebration of all of these aforementioned themes, and so it makes sense that the most widely distributed gifts on Valentine's Day are flowers.

Flowers are the perfect gift for someone that you are interested in and Valentine's Day is the perfect avenue for you to express yourself. Giving flowers to someone that you do not know so well might not be socially acceptable on other days of the year, but no so on Valentine's Day. It is accepted and understood that Valentine's Day is the yearly opportunity for us to truly express how we feel about any romantic feelings that we may have towards someone.
