Bramble leaves

Battered by Storm Callum. Ninety minutes running with eyes down glimpsing the occasional red leaf amongst the browns and yellows. The red of the bramble must be my favourite autumnal colour. Anthocyanins are chemicals found in the blackberries and synthesise in some of its leaves when sugar levels increase in the Autumn, giving them their red colour. On the other hand, carotenoid and flavonoid pigments give autumn leaves their yellow and orange hues. They are always present in leaves along with the green chlorophyll which dominates in the summer months. Come the cooler temperatures of Autumn, chlorophyll production decreases and existing amounts slowly break down thereby losing the green colouring. I couldn’t decide which leaf I liked best so I’ve hashed three photos together.
