Weird weather and fluctuating temperatures can have interesting affects on plants which is shown here by this stunning camellia currently flowering in a UK garden as the spring weather finally warms. This appears almost unreal but is the result of a natural genetic mutation – known as a chimera – that can change the appearance of the foliage, flowers, fruit or stems of any plant. Most mutations are random as a result of a change within the cells of the plant, but can sometimes be triggered by cold weather, temperature fluctuations or insect damage.
Are you noticing any similar changes to your plants as a result of the challenging weather experienced in the UK recently?
Apparently chimeras occur where there are two DNA lines in one creature or plant. Most living things only have one set of DNA, but through mutation, either natural or artificial, chimeras are born. All variegated plants are technically chimeras too. People or animals with blotchy, differently-patterned skin or two eyes of different colour could also be suspected chimeras.
