While dahlias produce anthocyanin, an element necessary for the production of the blue, to achieve a true blue color in a plant, the anthocyanin delphinidin needs six hydroxyl groups. To date, dahlias have only developed five, so the closest that breeders have come to achieving a "blue" specimen are variations of mauve, purples and lilac hues. [44]

If the leaves turn yellow and then drop, there may be low nitrogen in the soil. Adding a nitrogen-containing fertilizer or simply applying used coffee grounds around the plant might help as well.
