Not only did Meghan's bouquet have forget-me-nots in honor of Harry's late mother, Princess Diana — they were her favourite flowers — but her bouquet also featured sprigs of myrtle. Sprigs of myrtle are a royal tradition dating back to 1845 when Queen Victoria first planted them in one of her gardens. Queen Victoria also had myrtle in her bouquet, which is why she ended up planting them in the royal garden.
