Purple dahlia picture
The dahlia originated in Mexico and later became their national flower. However, it has a fascinating history through time in other countries, as well. In some parts of the world, it's been used for medicinal purposes and as a source of food. The dahlia has over 35 different species growing from 12" to 6' or better and the bloom sizes range from 2" to 12". Dahlias grow best in full sun and tubers should be planted in late spring. If you live in one of the colder climates, dahlia tubers should be dug up after the first frost and stored in a cool dry place in winter, then replanted next spring. My father-in-law used to grow and show dahlias as his hobby. Dahlias make great cut flowers because they last a long time and they're such pretty flowers.
