A blue rose does not exist naturally. Available in different hues or red, pink, orange, yellow and white, blue roses have never been naturally found in any part of the world. The worldwide fascination with the blue rose, that symbolizes mystery and the quest for the impossible, lead a team of Japanese researchers to genetically transform a standard rose bush to produce blue roses. However, the roses stopped being available commercially in 2009. The only way to attain blue roses is to dye white ones. Keep these tips in mind to produce blue roses.
Purchase an inexpensive container or vase from any home department store that you do not mind being stained with blue coloring. Depending on how many roses you want to dye, purchase either a cylindrical shape for a few stems, or a larger vase if you want several dozen blue roses. You can even purchase a clear glass vase for added effect.
Purchase Food Coloring
Food coloring in different colors is available in department and food stores. These are safer than commercial dyes since they are not harmful if inhaled or digested by children or pets. There are many hues of blue coloring available, ranging from a light sky blue to a deep navy blue. Select the one you want to dye your roses.
Fill Vase with Water and Apply Blue Coloring
Fill the vase with water at room temperature. Use a dripper to add coloring into the vase. Begin by adding several drops and let it dilute in the water, and continue adding drops until you get the desired color. The more color you add to the water, the deeper the blue coloring will be. If the water in the vase turns out darker than you want, simply turn it over to spill some out and add plain water.
Cut Rose Stems and Place in Vase
Go to your garden to select buds of white roses, so they absorb the blue coloring and bloom into blue roses. If you select mature roses they will only last a few days before they wilt or die. Make sure the rose stem is thick and free from dust mites or any visible pests or disease. It is crucial to cut the stems after the water is prepared to avoid them from drying. Roses dry out quickly, and may not absorb the color properly. However, if you pluck the roses before you mix the dye in water, keep them in a cool moist place, and mist them frequently to keep them from drying.
Hold a sharp pair of scissors or shears in one hand while you decide where on the stem you want to make the cut. Remember that a long stemmed rose looks beautiful; however, keep the height of your container or vase in mind so the roses compliment it. Make a straight diagonal cut on the stem, avoiding a jagged one that might prevent the rose from absorbing the color properly. Insert the rose stems into the colored water one by one.
