Cotton Candy Pink Dahlia Mexico’s national flower, many believe the Dahlia was named after Swedish botanist Anders Dahl. It is affectionately known as “queen of the autumn garden” because they bloom longer than most other garden plant varieties. Symbolically known for finding inner strength, remaining graceful and for standing out from the crowd, dahlias make the best gift for someone you perceive as a strong person or admire. Victorian’s believed dahlias to symbolise a lasting bond and lifelong commitment between two people and as such, make for a wonderful gift.
