Chrysanthemums are one of the most popular flowers in the world, next only to the Rose. Available in a rainbow of colours, each colour of Chrysanthemum symbolizes different things. For instance, red represents pure love; yellow Chrysanthemum depicts one-sided love while white symbolizes loyalty in love. To be genuinely hardy, they require time to establish themselves in the ground. Ideally, they are best planted in the spring and allowed to grow in place all season.
