from this month's Southern Living for those of us who live in Georgia highlighted how to dry hydrangeas. i feel like everyone has at least one hydrangea plant in their yard/garden and i always wondered how people maintained the color in the dried ones!
-use water (to preserve color)...cut blooms off of plant shortly after they peak, remove leaves, and place in a container with water covering 1/2 or less of the stems. after a few days, the water evaporates, drying the flowers.
-add Rit dye to your hydrangeas in denim blue or royal blue to give deeper color. add a few drops to the water and/or dab the petals with dye to enhance as well.
