How to Color a Rose Blue


Exuding uniqueness and mystery, the blue rose does not occur in nature as roses are absent of the pigment that produces blue. Therefore, roses must be dyed to achieve this uniquely symbolic color. Use a white rose for best results. Food coloring, ink and other dyeing mediums can be used to turn roses blue. Use a floral dye to achieve a deeper, uniform blue.

Step 1

Pour the ingredients for the dye solution into a spouted container. Fill the vase 3/4 full with lukewarm water. Empty the water into the spouted container. Add one packet of flower preservative and the dye to the water. Determine the amount of dye needed by following the directions included with the dye. Mix the ingredients in the container with a wooden spoon until the preservative and dye are dissolved.

Step 2

Pour the combined solution into the vase.

Step 3

Pour the hydration pretreatment into a shallow bowl, filling until 2 inches of solution is in the bowl.

Step 4

Hold the rose stems under lukewarm running water. Use a pair of clean, sharp garden shears to cut off the bottom 2 inches of the stem at an angle to allow for greater fluid uptake.

Step 5

Stick the stem end of each rose into the hydration pretreatment. Twist the stem, holding it upright, in a circular motion to cover the stem with solution.

Step 6

Place the stem end in the vase filled with solution. Roses will change to blue within 24 hours.
