Dahlias can produce a wide range of color depending on the color of the flower, and even white dahlias will produce a color (light yellow). When harvesting, separate out the flowers by color for drying. It is suggested to harvest the dahlias in the cool morning for best results. The flower will come off easily from the stem of the plant if pulled from the base of the flower. These flowers are highly productive, so it is important to harvest often.
These are dense flowers so it is important to keep them dry and cool once harvesting to prevent mold from growing from trapped in moisture in the center of the flower.
