In Roman mythology, Flora is a goddess of flowers and Spring.  She is one of several fertility goddesses.  Her festival, the Floralia, was held between April 28 and May 3 and symbolized the renewal of the cycle of life, drinking, and flowers. The festival was first instituted in 240 BC.  Flora was married to Favonius, the wind god, and her companion was Hercules. 

She enjoyed a revival in the Renaissance period, and was the subject of paintings and ballets.  Her Greek equivalent is Chloris, although she is a nymph and not a goddess.
