The magical allure of autumn

Autumn conjures up images of trees changing colour, chill mornings and wrapping your hand around a mug of hot chocolate. Traditionally autumn was a time to harvest crops, stockpiling food for winter and celebrating the harvest. Yet autumn is also a time of abundance and beauty. This we find in the stunning colours we get from the plant’s leaf colour changing. In this article, I will have a look at why leaf colour changes, highlight plants with colourful foliage during autumn and suggest some beautiful flowering plants for this time of year.

Why do leaves change colour?

  • Leaf colour is determined by 3 pigments in the cells, which alter the colour that we see leaves as.
  • Chlorophyll is responsible for the green we see and the most important function in leaves – which is photosynthesis.
  • Carotenoids come through as yellow and at times a slightly orange colour.
  •  Anthocyanins give leaves a red to purple colour.
  • As the day length decreases, plants produce less chlorophyll with higher concentrations of the other two pigments. That is why plants such holy bamboo changes its leaf colour to the most amazing autumn shades.
  • Deciduous trees and shrubs manage to recycle the chlorophyll in leaves before they drop, leaving the other two pigments in prominence, gracing us with their colour.
