Is It Possible To Grow Your Own True Blue Flowers?

Blue flowers are uncommon and rather not easy to find, simply because to get the true blue colors, the plants have to do the ‘light trick’ by reflecting the sunlight to achieve the color blue. But we’re living in the 21st century, is it possible to change, let’s say, red roses to blue ones?

Unfortunately, the answer to this is still unlikely. There’s no one, even the most genius scientist and gardener, that can do this genetic mutation. However, this phenomenon could become a reality as more genetic engineering scientists from recent research have been trying to find the key answer to create more true blue flowers. As for now, we are still able to appreciate the beauty of blue blooms by sowing flowers that naturally have shades of blue in their genetic code.
