Sometimes you have received or bought Blue Roses and you wonder if they are natural. In nature, natural Roses are White, Pink, Red and Yellow, while Blue Roses are the product of man's ingenuity. In this post, you will be able to read the history of Blue Roses, where to buy them, how they are grown and other information.
Origin of Blue Roses
If you have seen, among the objects of your grandparents and parents, cards to wish a happy birthday, or congratulations on success in studies, you will see drawings of beautiful bouquets with many roses of different colors and among these the blue Roses. Also in the literature, especially in the era of romanticism, there was talk of the Blue Roses and their relationship with the achievement of embarrassing or difficult objectives. As well as its meaning of dreaming of these flowers.
At that time, there was talk of a Blue Rose known by the name "Veilchenblau" of German origin, which was not actually blue as such, but was Pink with a grayish tone color that according to exposure to light sunlight came to see a bluish color and its shape was also different from the Roses that most of us know. It should be noted that the original roses are different from those known today, since these flowers are mostly hybrids.
In nature, the colors of the Roses are white, Pink, Red and Yellow, which depend on the quantity and type of pigments that the species of Roses contain. On the other hand, Blue Roses do not exist naturally, those that are known are of artificial origin, since they were obtained by the intervention of human beings. Blue Roses began to be marketed at the end of the XNUMXth century, but it is in the XNUMXst century that a genetically modified variety was obtained through biotechnology.
In the final years of the XNUMXth century, Blue Roses were commercialized, they were obtained by placing White Roses in water dyed with blue food coloring or also those that applied the blue color with an aerosol. Of course, if you wanted to propagate these Roses, Roses were born with the original color and it was not exactly the color Blue. Unlike those obtained with biotechnology techniques, in which you alter the original color of the Rose by incorporating a gene with the color Blue, which when propagated you obtain Blue Roses.
At the beginning of the 2004st century in the year XNUMX, in a whiskey distillery it was possible to obtain the Blue Roses artificially. This was achieved in the company with biotechnological projects of Australian origin called "Florigene". The rose variety obtained was achieved by grafting the natural gene that develops the blue color "delphinidin" into roses obtained from petunia plants, which are the only blue flowers in nature. The Blue Rose variety is called “Blue Moon”.
The Australian company Florigene was sponsored by a Japanese company called Suntory Ltd, a beverage company. Florigene managed to isolate the gene that provides the color blue in nature. However, although the DNA of these “Blue Moon” Roses was altered, their color is a pale bluish purple.
When observing this variety you will notice that it is violet in color, this being the blue color that you will see in these Roses. The researchers continue their investigations to achieve a more defined Blue color. Obtaining the varieties, “Blue Bajou, Blue for You”, Rhapsody in Blue and Blue Eden and others. However, they all bloom with Roses of different shades of violet or light lavender.
This in order to please consumers who ask for Blue Rose plants, without undermining the fact that the “Blue Moon” variety was very well received. These biotechnological investigations will allow obtaining Blue Roses, which negatively impact other natural resources such as water and soil as little as possible to obtain Blue Rose flowers that later, when flowering ends and wanting to propagate, Rose plants of other natural colors are born, such as red, white, yellow or pink.
Presentation to the public
The Japanese company Suntory, announced to the public the Blue Roses obtained by biotechnology, at the Flower Exhibition held in Tokyo in 2009 and that same year they began their commercialization. Today this company is responsible for marketing roses obtained through biotechnology or in vitro cultivation worldwide.
In order for the Roses to maintain their bluish coloration, the investigations were oriented to preserve the blue color. This was achieved shortly after the commercialization of Blue Roses obtained through biotechnology began. This was achieved by subjecting the varieties obtained to a chemical treatment in order to protect their precious color and their particular types.
The demonstration of the feelings of love in different ways such as affection, solidarity, friendship and sexual love, through flowers usually has a particular meaning and if these flowers are Roses, their meaning is very special in personal life. who offers them and who receives them. The color of Roses varies according to their color such as white which means purity and fraternity, yellow which indicates friendship, good energy and optimism and of course the red ones which mean passionate love.
According to this, what is the meaning of the Blue Roses? Knowing the meaning of flowers is a way of relating since ancient times, which allows without saying a word to express the feelings you feel towards another person. This way of communicating originated in France, it is a romantic and seductive language that quickly spread to other countries.
Blue Roses are the most expensive because they are a variety obtained in in vitro culture or biotechnology laboratories, and even those obtained with blue dye, in both cases are difficult to obtain. Whoever gives them knows their meaning and offers them to a very special person. Blue color is associated with mystery. To love with little chance of achieving it, to an idealized dream. Likewise, Blue Rose tattoos indicate beauty.
It also means that the Pink Roses are the most sought after varieties of Roses because it means that dreams are attainable. They also indicate that its meaning refers to liberating, relaxing feelings, loyalty and security. When you decorate the house with Blue Roses, an atmosphere of harmony and peace is obtained. If you want harmony in the relationship with your partner or family and friend, by giving Blue Roses, you are telling him or her that you believe in him or her and that your love is lasting.
Like all Roses, these plants need a lot of sun to grow, the ground is prepared by removing the weeds, placing fertilizer or nutrients for Roses and when you have the rose bushes it is suggested to soak the rose bushes for about 12 to 24 hours to rehydrate, before sowing it in the place of destination. Remember to have your gardening tools, protective glasses, safety gloves at hand.
When you prepare the soil, make mounds of about 30 centimeters, to place the plants a little higher and walk through the lower space to maintain the crop. The planting distance between plants is about 70 to 90 centimeters between plants. Planting holes must measure 15 centimeters wide and deep. Once the Blue Roses are planted, secure it with a little soil and then water it, the soil must be moist but not flooded.
An irrigation frequency is recommended every two weeks or when you see the soil dry. The rose bush is fertilized the third month after the Blue Roses are planted, the fertilizer you use must have a special formula for Roses. The indications of its dose and how to apply it is indicated on the product label, if you want to obtain beautiful Roses follow the manufacturer's instructions.
During the maintenance of the rosebush, care must be taken to control weeds or weeds, so that they do not compete with the crop. The cultivation cycle of Roses is about 3 and a half years. When harvesting the rosebush at the end of spring and beginning of summer, in countries with temperate climates, when harvesting, the branches must be cut to a third. It is appropriate to keep track of the harvest date in order to harvest the Blue Roses at the right time and enjoy them.
Acquire Blue Roses
The Japanese company Suntory Ltd, has the patent for Blue Roses, after presenting the first Blue Rose called Blue Moon, obtained by in vitro culture, in Tokyo at the Flower Fair. This company markets them in Japan, the United States and Canada. Few florists have permission to sell the Blue Moon Hybrid Rose. The color of this Blue Rose is more purple than blue, its creators indicate that its flowers will turn intense blue. Less expensive Blue Roses painted with blue dye are also offered for sale.
Rosebush of Blue Roses
The fact of growing a rosebush of Blue Roses in the garden of your house, will allow you to have a spectacular place in your own garden. As you know how to grow flowers, they have to have a special treatment and especially Roses. In addition to pruning, watering and watering in a timely manner, these flowers like to be treated in a special way, with love and subtlety during their growth.
However, these flowers like to be treated delicately, but this plant is not very delicate. You have to be very careful when handling it, because of its thorns. These thorns, that more than one knows when he buys Roses to make and is handling them, more than once he will have felt their thorns, and bled a little.
These stingers are their defense against animals. When the flower bud opens, the Roses sprout concentrically and this makes them very attractive flowers. These thorns indicate that even though Roses are very beautiful flowers, they are also strong and know how to defend themselves. As if nature expressed the Yin and Yan of these flowers, wanting to show the antagonism of each living being, such as light and darkness, the beautiful and the ugly. That beauty can also have its painful side.
Blue Rose Trend
Since their commercialization in 2009, Blue Roses, due to their original color, beautiful and delicate, have become a trend in gardening and florists. In some cultures, brides traditionally wear something blue as a talisman for a good marriage, and Blue Roses are good options to make the bridal bouquet and fulfill this custom.
Fashion designers are inspired by its beauty, the subtlety of its petals and the strength of its stingers and color. They prepared the color blue to be a trend in fashion by taking the beauty of Blue Roses to create a style with a sweet, urban and fine touch. Likewise, in the gardens there has also been a trend in the growers of Roses of different colors and varieties, gardening workshops are held to teach how to grow and have your own rosebush with Blue Rose flowers at home.
dyed blue roses
In order to meet the requirements of consumers, before the biotechnologists of the company in Australia "Florigene", with Japanese financing Suntory Ltd, managed to isolate the gene that gives the blue color in flowers. Rose horticulturists managed to dye the petals of white Roses with a blue dye and market them. So that you have Blue Roses at home, I will show you step by step how to obtain dyed Blue Roses at home.
Materials you need to have: A large pot, a vase, rainwater or lime-free water, Blue food or baking coloring, and a plastic stirring spoon preferably. In addition, the main ingredient is white rose flowers. Once you have all the materials, disposition and time. Follow the following steps of the process of dyeing the Roses and obtain Blue Roses to decorate the house or give to a loved one.
It's very easy, follow these steps, start by filling the pot with rainwater (if you don't have rainwater, use water without lime), about ¾ of the pot; Proceed, apply about 3 drops of Blue color dye, once applied the dye begins to stir so that it mixes well and if you want darker Blue Roses, add about 3 more drops.
Already the water with the dye or dye proceeds to cut the stems of the white Roses, the cut has to be diagonally at the base of the stem. Roses are placed in water with dye or coloring for two days. After two days, he passes the dyed Blue Roses to the definitive vase. The time that they last open and in good condition, will depend on the variety of white Roses that you dyed.
Varieties of Blue Roses
At the end of the 1980th century, in the XNUMXs, significant advances were made in plant genetics and biotechnology research. These achievements motivated the researchers to produce new varieties of plants that, in addition to making varieties resistant to pests and diseases, sought to change the colors of their flowers, the beauty and duration of their flowering, and other changes.
These technological changes spread to different countries and, already in the 1990s, many food producing companies hired their own teams of plant geneticists to dedicate themselves to genetically improving the plants of their interest, such as obtaining Blue Roses. Achieving this would be a great advance and first the gene or genes that would provide the blue color to flowers in nature had to be isolated, in order to analyze the blue pigment.
Once this first challenge had been overcome, there was another challenge to achieve, incorporating this gene into the genetics of the Roses and being able to obtain genetically modified Roses. Being the first to reach these steps was a challenge for flower biotechnologists and geneticists, and especially for the financiers of these projects, because once they did, they would be patented, and the third challenge was to be the first to have the answer and patent.
Successfully isolate genes taken from petunia plants
In nature there are few plants that produce blue flowers, and after carrying out the pertinent investigations, the biotechnologists opted for the Petunia sp. dark violet. Petunias plants have in their genetic composition about 30.000 genes, of which about 300 were chosen to investigate, of these, after analysis, the 2 genes that provide the violet color of their flowers were selected.
Part of the research dealt with once the genes that provide color to the flowers of this plant were obtained, incorporating these genes into Petunias plants with flowers of other colors and keeping track of the color change of the flowers. This step was delayed depending on the time that the plants bloomed and the flower buds opened to observe if there was a change in color and if the blue color was obtained in the flowers.
To speed up this step, the researchers took the genes under investigation and incorporated them into yeast. In this case, the results could be seen after two weeks, by mixing the genes with yeast and getting to know how these genes act in less time. In June 1991, the Japanese company Suntory Ltd, through the Australian laboratory Florigene, succeeded in isolating the “delphinidin” gene for the first time, then applied for a patent on this gene and obtained it. Making the Blue Moon Blue Roses public in 2009.
Process of incorporating the “delphinidin” gene in Roses
The method applied by the geneticists of the project to obtain the Blue Rose was through the use of soil bacteria Agrobacterium as carrier of the isolated gene. The selection of this bacterium was because the agrobacterium, it transplants its genes into plants and is used by genetic researchers to carry out gene transfer into other plants. During the process, a meticulous control of the nutrients and hormones that are supplied to the plants is carried out.
Regarding the experiment with the Roses, due to the life cycle of these plants, it took a period of approximately one year to obtain the first flowers in a genetically modified plant. In addition to this, observing the results of the genes incorporated into the plants could vary depending on the species treated and also between individuals of the same species.
After several processes, it was possible in 1994 to introduce the "delphinidin" gene obtained from the petunias sp., in Red Roses and then when opening the flower buds, Red Roses were obtained without showing Blue pigmentation. To continue their search for Blue Roses, the researchers considered it opportune to isolate the genes that provide the Blue color in gentian, clitoria and torenia plants to incorporate them into Rose plants. Result Genetically modified roses that have genes for the color blue, but the flower buds did not show the color blue in their petals.
The genetic researchers were concerned that the goal of the research remained unattainable. They tried incorporating the isolated gene "delfinidin" into carnation plants and obtaining genetically modified carnations. Unlike the Roses that did not show the Blue color in their flowers, the Carnation flowers responded as expected with flowers with Blue petals.
In this case the "delphinidin" genes were collected and the color of the flowers changed to Blue. This motivated biotechnologists to continue advancing in research and sought to isolate the genes that promote the blue color in thought plants. They continued to investigate until they achieved what was expected.
Finally the Blue Roses
The time came when the flower buds of the Roses were observed with a Blue pigmentation. This was observed when the red roses that were used for the research opened with darker red petals. The objective was still to be achieved, the Blue Roses, and the fact of achieving the appearance of the Blue color in the petals directs the research towards the new Blue Roses.
This allowed us to start studying what other factors besides the pigment that promotes the blue color? Obtaining that the pH of the vascular cells and also the enzymes improve or worsen the manifestation of the blue color in the flowers. Biotechnologists continued gene research, isolating thought genes, incorporating them into the plant tissues of some 40 different Rose species, and simultaneously improving plant breeding procedures.
For the years between 1998 and 1999, the flower buds of the first Bluish Roses began to emerge. For the year 2000 of the 100st century, rose blooms were obtained with XNUMX% flowers with blue pigments. Obtaining the first Blue Roses on the planet. They continued testing the asexual propagation of the Blue Roses, through grafting and the plants that were formed were unalterable and easy to grow.
The objective had already been met, now it had to be resolved how to market these plants or flowers so that consumers would know about them. In view of this, the Japanese company Suntory Ltd., responsible for having achieved Blue Roses by the method of biotechnology and altering the genetics of plants. It had to obtain authorization from the Ministry of Agriculture for the Law of Conservation and Sustainable Use of Biological Diversity-Cartagena protocol, to allow commercial planting and marketing of plants and flowers.
This delayed its appearance in public, in view of this the company carried out several investigations to explain why the Blue Roses achieved by the Japanese company did not negatively impact biodiversity. This meant that for four years they were making crosses, cross-pollination between Blue Rose plants with plants of other wild species of Roses.
With this clarify that the genes of the Blue Roses will not alter the genetics of other plants with which they are crossed. In 2008, they authorized their public presentation and marketing. The first Blue Rose obtained on the planet was called Blue Moon and it was in 2009, after being presented to the public, that its commercialization began.
Finding the really blue rose
In 2009, the companies Florigene (Australia) and Suntory Ltd. (Japan) presented in partnership the first genetically modified Rose to produce the biosynthesis of "delphinidin", and marketed by Suntory, known as Blue Moon, which was very well received by consumers. consumers and, which is still more purple than blue.
The Japanese company continues its studies, determining that the blue color in nature is conditioned by other environmental and physiological factors of the plants. Until Dr. Zhang's team decided to use a different pigment, biosynthesizing the Rose and making it produce the pigment "indigoidin", a pigment that paints blue and has antimicrobial and antioxidant characteristics.
The research continued with the creation of a circle of DNA, which they called a plasmid, made up of two bacterial genes that are part of the biosynthesis of indigoidin. This plasmid, together with two enzymes generated by these genes, forms L-glutamine, which is an amino acid present in abundance in the petals of Blue Roses.
The next step was to incorporate the plasmid into the Agrobacterium bacterium, then inject it to be taken up by the white Roses, both the Agrobacterium and acetosyringone, to catalyze gene transfer. After 12 hours, the rose petal was colored intense blue and the presence of indigoidine was verified by spectroscopic means. Several varieties of Blue Roses are known, namely: "Blue Bajou, Blue for You", Rhapsody in Blue and Blue Eden and others.
