Fresh flowers and how they get their colour
Whether you take a walk through a lush garden or go to your local florist, you’re sure to notice flowers of various colours. Some fresh flowers come in almost every colour and even in different shades of each colour. There are also multi-coloured flowers that are particularly interesting. Nature has us to thank for most of the colourful flowers we have today. However, man has been known to get involved from time to time to grow his favourite flower in a colour not found in nature.
The flower colours are due to something called anthocyanidins. These compounds are named after the flower they are found in and are all different. Petunidin is the purple compound found in petunias, and thanks to modern technology, scientists can manipulate other fresh flowers using this anthocyanidin. For example, the compounds extracted from the deliticinesis can be used to create impressive blue carnations.
When the anthocyanidine is combined with the sugar that is naturally found in plants, the result is anthocyanins. It is anthocyanin that makes the leaves change colour in autumn, while chlorophyll gives them their green colour.
The reason for bright shades
The plants produce beautiful, fresh flowers to attract insects and birds. When the creatures arrive to enjoy the flower’s nectar, they leave covered in pollen. This is how pollen is transmitted from one flower to another and is an essential part of the plant reproduction process. Once pollinated, the flower will change colour. This is a clear signal to insects and birds that they should look for another flower.
Bright versus low light
Another factor that can also influence the colour and shade of a flower is light. It is important to keep in mind that it is not the colour of the flower that changes, but rather our perception of colour. colours appear different in bright light than in low light. Additionally, the pH level of the soil can directly affect flower colour. Just look at the hydrangeas. They produce fresh flowers in different colours depending on the pH level of the soil.
While there are some common factors that will influence the shades produced by particular plants, there are also some other factors that are unique to specific plants. If you are not able to find fresh flowers in the colour you desire, remember there are always flower-safe dyes or paint.
