The blue rose is a highly sought-after floral item that remains naturally elusive in horticulture. Roses of the genus Rosa cannot synthesize the blue pigment, making a truly blue shade impossible without human intervention. This natural limitation has historically made the blue rose a symbol of mystery or the unattainable, driving consistent demand. Acquiring and maintaining these flowers involves recognizing the two primary forms they take when sold.
Understanding the Color: Dyed vs. Genetically Modified Roses
Since roses lack the gene required to produce the blue pigment delphinidin, the vast majority of blue roses available commercially are created artificially. This standard method involves taking a white or light-colored rose and allowing it to absorb a specialized blue floral dye through its stem. The dye travels through the plant’s vascular system, coloring the petals from the inside out, resulting in a vibrant, often electric, blue hue.
The color consistency of dyed roses can vary, frequently leaving traces of the original white color visible near the base of the petals or along the edges. This process is the most common and affordable option for consumers seeking a bold blue flower. A less common but scientifically significant alternative exists in the form of genetically engineered roses.
The genetically modified blue rose, sold under the brand name ‘Applause’ by Suntory, was created by inserting the delphinidin gene from a pansy into a rose’s DNA. The rose’s petals contain natural acids that chemically alter the pigment, meaning the ‘Applause’ rose presents a color closer to a soft violet-blue or mauve, rather than a true cerulean blue. These blooms are a specialized, luxury product, often reserved for high-end arrangements and select markets.
Primary Sources for Purchasing Blue Roses
The source for purchasing blue roses depends on whether the consumer seeks the vibrant dyed variety or the rare, genetically engineered bloom. Large national and international online florists are the most reliable source for the dyed blue roses, which are available year-round and offered in bulk quantities. These vendors can reliably deliver the flowers quickly, though shipping costs must be factored into the final price.
For consumers seeking the ‘Applause’ rose, the purchasing process is restricted and requires a targeted approach through specialized florists. Due to their limited supply chain, these genetically engineered roses are only available through select, authorized florists who have established relationships with the supplier. The price difference is substantial; while a dozen dyed blue roses are comparable to standard-colored roses, a single stem of the ‘Applause’ rose can cost between $22 and $33.
Local flower shops may not keep dyed blue roses in stock, but many can create them on request, provided a few days’ notice is given for the dyeing process. Preserved blue roses, which are chemically treated to maintain their appearance for months or years, are available from specialty vendors who sell them in decorative boxes. The logistics for the ‘Applause’ rose often involve direct consultation with a high-end florist to confirm availability and shipping timelines.
Care Instructions for Extended Freshness
Once the blue roses arrive, immediate attention to hydration and preparation can significantly extend their vase life. The first step involves cutting the stems at a 45-degree angle while holding them under lukewarm water to prevent air bubbles from blocking water uptake, a process known as air-lock. Lukewarm water is preferred because it allows for more rapid initial hydration.
The cut roses should be placed in a clean vase filled with fresh water mixed with a commercial flower food packet. This food typically contains sugar for nutrition, an acid to aid water absorption, and a biocide to inhibit bacterial growth. Any foliage that would sit below the waterline must be removed to prevent decay and contamination of the water.
A unique consideration for the common dyed blue roses is the potential for the color to transfer. As the rose continues to absorb the dye, the vase water will likely become tinted blue, which is a normal occurrence. To prevent potential staining, handle the stems gently and place the arrangement away from direct sunlight, heat sources, or drafts, which cause rapid dehydration.
