People give flowers to other people to show love, affection, admiration, gratitude, and other emotions. People also gift flowers on special occasions, such as birthdays and weddings. The tradition of giving flowers started in prehistoric times. People saw flowers as healing, so they were first used as sacrificial and burial items. Records show that ancient Egyptians, Greeks, Romans, and Chinese practiced the act of giving flowers. Gifting flowers among couples to show love became established around the Middle Ages.
