A blue rose is a flower of the genus Rosa (family Rosaceae) that presents blue-to-violet pigmentation instead of the more common red, white, or yellow, through use of artificial means such as dyes. Blue roses are often used to symbolize mystery or the unattainable, [ 1 ] since they do not exist in nature because of genetic limitations.
Additionally, the pH of blue cell is around 4,1 and red is lower around 3,3. This supramolecule is relatively unstable and easily can fall apart in result of change of component concentration or pH conditions, so this can explain why blue colour in hydrangea sepals has low stability.

A blue flower (German: Blaue Blume) was a central symbol of inspiration for the Romanticism movement, and remains an enduring motif in Western art today. [1] It stands for desire , love , and the metaphysical striving for the infinite and unreachable.
There are no truly blue anemones, despite the frequent use of the label "blue" in marketing to describe blue-violet flowers (flowers that are more violet than blue). Color labelling inaccuracy in marketing is found in treatments of numerous other genera, especially as it concerns the color blue — although some popular garden flowers from the ...
Ipomoea indica flowers change from bright blue to a faded purple by the end of the day. [2] Hibiscus mutabilis flowers changing colors during a day. Floral color change occurs in flowers in a wide range of angiosperm taxa that undergo a color change associated with their age, or after successful pollination. [3] [4]
Each flower is 14–20 mm (0.55–0.79 in) long, with two bracts at the base, and the six tepals are strongly recurved at their tips. [8] The tepals are violet–blue. [12] The three stamens in the outer whorl are fused to the perianth for more than 75% of their length, and bear cream-coloured pollen. [8] The flowers are strongly and sweetly ...
If there are species with true (neutral) blue or greenish-blue flowers they are rare and do not occur in cultivation. Also unlike the genus Delphinium, there are no bright red nor intense pink Aconitum flowers, as none known are pollinated by hummingbirds. There are no orange-flowered varieties nor any that are green.
While sometimes dyed blue for cut bouquets, there are no known carnation cultivars that produce a true blue flower. The fragrant, hermaphrodite flowers have a radial symmetry. The four to six surrounding the calyx, egg-shaped, sting-pointed scales leaves are only ¼ as long as the calyx tube. [5] [9]
