Make a Rainbow Rose
It's quite easy.
PREPARING THE ROSE
1. Trim the stem
Cut the stem of the rose down so that it is roughly the length you want it to be. Use sharp scissors or a sharp knife to cut the bottom of the stem at an angle. To determine the proper length, base the stem height on the height of the containers you will be dyeing the rose in or the height of the vase you plan to store the rose in afterward. The stem of the rose needs to be only a little taller than the length of the final vase. It should not be too much taller than the height of the dyeing containers though, or else the rose will become top-heavy and will not sit well inside the containers.
2. Split the stem into sections
Use a sharp blade to split the end of the stem into multiple sections. You can use either scissors or a knife, but either way, the tool you choose must be sharp. The stem of a rose is fairly woody, and if you use a dull blade, you could end up causing the stem to break or tear the rose. The cut should extend from the bottom of the rose up to about 1 inch (2.5 cm) away from the base of the petals.
3. Divide the stem into two to four sections
If you cut too many sections into the stem, you risk weakening the stem. Note that the number of sections you cut the stem into will determine the number of colors in your rainbow rose.
Adding the colors
1. Mix several colors of food coloring into cups of water
Fill a few tall, narrow containers with water and mix in a few drops of food coloring into each container. Choose one different color for each container. As mentioned already, the number of colors should match the number of sections you split the stem into. The more food coloring you use, the brighter the colors will be in the resulting rainbow rose. The best containers will be narrow and sturdy. Avoid using containers with wide lips since the split sections of stem will need to stretch into each container, and wider lips might be harder to stretch the stem sections into. A popsicle mold works well, as do small votive glasses.
2. Place each stem section into a different container
Carefully place each split stem section into a different container of colored water, making sure that the cut ends are fully immersed. Exercise extra caution when bending and positioning the stem sections. The split stem is especially weak, and if you move the sections with too much force, you might end up snapping them by accident.
3. Position the containers of colored water directly next to each other
This will keep the entire structure more secure and limit the amount of space you need to stretch the stems over.
4. Let the roses sit for a few days
You should notice some color change within the first 30 minutes, but for a vibrant rainbow rose, you will need to let the rose sit in its dye bath for a few days. It may take a full week before the colors become notably vibrant, but after a single day, each of the petals should be tinted with color. The dyed water will be absorbed through the stem of the rose just like standard water would be taken in. As the dyed water travels throughout the parts of the rose and hydrates the petals, the dye will be deposited in the petals. Since the petals are white, the dye shows through easily.
