Why are flowers and plants different colours?

And how are they different colours? I've got a rose in my garden (I've got a few actually), it's a pinky colour, but it should be blue, any idea how I can get it to be blue?

Thank you for answering. :)

Why are flowers and plants different colours?
Many flowers have developed colors to attract beneficial insect or birds to their pollen and polinize other flowers, some colors are to warn or to make predators get away or at least make them thing. Know it have been seen in UV cameras , that many yellows color in flower are captured in UV so birds and insect can see them also!..In green plants the variation depends in the chlorophyll (green pigment) how much sun light they receive also, the soil conditions and some parts of the leaf lack chlorophyll and other have another pigments that give them this red or purpish color.

Now, they are many variation because man has modified plant genetically also.

About your Rose, have it give blue color before? If not check very well if you have the right one. And is your rose fully grown?
Reply:I am not a gardening expert but i think it has something to do with the acidity or the alkalinity of the soil. Ask a garden centre or go to B%26amp;Q and ask their garden department what the PH of the soil should be and what you can add to get it correct.
Reply:As flowers attract bees for a purpose of pollination, they do this beautifully. They seem to know how to charm and entice nature for a purpose. They know exactly what colours to show off and what patterns to assume to be noticed and appreciated in this grand masquerade of nature where all purposes are concealed behind ever so more luring shapes and forms. If just by being purposeful flowers look beautiful then we should understand that nature appreciates beauty, as we know it. And if nature appreciates beauty then nature is beautiful.



What we see in flowers is essentially what flowers see in nature – condensed beauty and purposefully expressed. If the beauty of nature is in the honesty of its purpose then flowers reflect this perfectly well like a mirror. It is true that it is free for us to see and enjoy but it is not vain or without its purpose. We see all this but we are not able to locate a single intelligent mind either in flower bearing plants or anywhere else in nature, and yet all this happens. Where is then the mind that makes this all happen?



And then we notice all flowers are not the same. The delicate tapestry of fauna and flora stretched on the bosom of this earth is not lacking in its range or variety. There are flowers of all sorts. There are trees of all sizes. And there are bees and insects of all kinds that depend on flowers, and birds of huge variety that dwell on trees.



I can say that flowers are somewhat like us. They may have similar purposes but their needs are specific. Some like to blossom in the morning – like Morning Glory; some like to constantly look towards the Sun – like Sunflower; and some simply would not live without banks of lacks and rivers – like Water Lilly. Some like to grow in hills while others prefer to blossom in the mellowness of temperate vales. They need to have insect companions who are happy in these conditions. They express their needs in terms of their coloration and specific shape and formation of their petals. In general what they look like is a beautiful or an agreement between their specific needs and their environment. You can for example have red roses, and then you can have crimson, white and pink. This is sweet and true. But if you live in water and want your roses in blue then make sure you have bees that swim, and are also madly in blue.

Reply:To attrack different insects and that way be able to reproduce and expand.

I know that you can change the colour of some flowers by adding products(that usually are sold in garden centers) in the water or in the soil. I know that is better if the flower is white, I don't know how well it would work with pink.

(You can always try to spray them with food colouring :-P)
