Almost like magic, you can change the color of white flowers just for fun, or to match your decor or an event. White carnations, roses, daisies, Queen Ann's lace, and many other flowers are perfect for dying. Experimenting with different white flowers, different intensities of the dye water's color and the length of time your white flower stems stay in the dyed water can create some surprising and stunning results.
From White to Custom-Colored Flowers
Prepare your colored-flower water by filling your vase or container with warm water. Warm water is better for your cut flowers than cool or cold, and will help them last longer.
Add food coloring to your vase water to create the color hue you want your white flowers to become. Usually 10 to 20 drops of food coloring to your water is sufficient, depending on the amount of water you have in the vase and the intensity of the color you want your flower to acquire. The more food coloring you add, the deeper a shade the petal color will be. You can also mix food coloring to create the hue you want, for example red and blue will make purple. More red than blue creates burgundy or maroon.
Add 1/2 to 1 teaspoon of sugar to your colored water, which will be food for your cut flowers. Sugar also helps your flowers take up through their stems more water, which will help color your white flowers faster and more completely.
Use a sharp knife to trim 1 to 2 inches off the ends of the stems of your white flowers. Cut your stem ends at a 45-degree angle to create the maximum area of exposed stem end for water absorption.
Place your freshly cut flower stems in the vase of colored water. Check on your cut flowers after one or two hours to see how much color change has occurred. Continue to monitor your flowers for color change every hour. It may take up to 24 hours for your white flowers to completely and thoroughly change colors.
