"Basics of white flower colouration White flower colour is related to the absence or reduction of the anthocyanidin content. Unlike other colors, white colour is not induced by pigments. Several white plant tissues are principally equipped with the complete machinery for anthocyanin biosynthesis including the expression of regulatory genes. Nevertheless, they are unable to accumulate red or blue pigments, for example Dahlia ´Seattle´ petals showing a white tip. Several studies have revealed a further reduction of the anthocyanidin to colorless epicatechin by the enzyme anthocyanidin reductase (ANR). Many external factors can influence colour: light, temperature, pH, sugars and metals. There"
"Leontopodium nivale Leontopodium nivale, commonly called edelweiss (English pronunciation ), is a mountain flower belonging to the daisy or sunflower family Asteraceae. The plant prefers rocky limestone places at about altitude. It is non-toxic and has been used in traditional medicine as a remedy against abdominal and respiratory diseases. The dense hair appears to protect the plant from cold, aridity, and ultraviolet radiation. It is a scarce, short-lived flower found in remote mountain areas and has been used as a symbol for alpinism, for rugged beauty and purity associated with the Alps and Carpathians, and as a national symbol, especially"

The flowers bloom between July and September. ""Leontopodium nivale"" is considered a least concern species by the IUCN. The population of this species declined due to overcollection, but is now protected by laws, ex situ conservation and occurrence in national parks. ""Leontopodium nivale"" is"

Because of its ties to royalty, authors such as Theodor Fontane have used it symbolically, often sarcastically, to comment on the social and political climate of the time. The cornflower is also often seen as an inspiration for the German Romantic symbol of the Blue Flower. Due to its traditional association with Germany, the cornflower has been made the official symbol of the annual German-American Steuben Parade. In France the is the symbol of"

Compounds of different classes, such as terpenoids, phenylpropanoids, fatty acids and polyacetylenes are reported in various parts of edelweiss plants.

In Berthold Auerbach's novel ""Edelweiss"" (1861), the difficulty for an alpinist to acquire an edelweiss flower was exaggerated to the point of claiming: ""the possession of one is a"
"Edelweiss (grape) Edelweiss is a very winter-hardy wine grape variety, pale green in color, derived from crossing the Minnesota 78 and Ontario grapes. It was developed by Elmer Swenson in 1980 in cooperation with the University of Minnesota. The clusters are large and rather loose, weighing a pound or more. Early picking of the grape is essential for making a wine. Should Edelweiss not be harvested early, the completely ripe ""Vitis labrusca"" flavoring becomes too strong for the palate of most. Edelweiss was first developed as a table grape. This variety bears the Minnesota winters, but mulching is encouraged. During"

"Blue rose 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. Blue roses are often portrayed in literature and art as symbols of love, prosperity, or immortality. However, because of genetic limitations, they do not exist in nature. In 2004, researchers used genetic modification to create roses that contain the blue pigment delphinidin. So-called ""blue roses"" have been bred by conventional hybridization methods, but the results, such as ""Blue Moon"", are more accurately described as lilac in color. Since blue roses do not exist"

The large, strongly fragrant red and white flowers have a high-centered bloom form and appear continuously throughout the season. They are double, have a diameter of more than 10 cm (4"") and up to 30 petals. In the sun, their colour changes from white to carmine red, beginning at the edges. The change is therefore more"

This resulted in an entirely new colour range for roses: shades of deep yellow, apricot, copper, orange, true scarlet, yellow bicolours, lavender, gray, and even brown were now possible. Originally considered a separate class, the Pernetianas or Hybrid Foetidas were officially merged into the Hybrid Teas in 1930. The new colour range did much to increase hybrid tea popularity in the 20th century, but these colours came at a price: ""Rosa foetida"" also passed on a tendency toward disease-susceptibility, scentless blooms, and an intolerance of"
