Sure, roses are the flower of love, but they're not the only variety that are romantic. Show your valentine how much you really care with a bouquet of peonies, sunflowers, or tulips this year, which symbolize happiness, prosperity, and romance. According to FTD Flowers , these fluffy blooms are most commonly associated with romance , prosperity, and bashfulness. Some even believe they're a good luck charm of sorts, bringing good fortune to whoever receives them. Peonies also have some roots in Greek mythology: as one myth states, Apollo used to turn beautiful nymphs into peonies if Aphrodite, the goddess of love and beauty, knew he was flirting with them.
