At Trentham Gardens today.
Red leaves on plants at Trentham Gardens today. Usually leaves are green but these have a strong red colour. The light shines through them giving them a glow. I remember hearing about other plant colours that happen in autumn. The green chlorophyll is absorbed back into the plant (usually a tree) and other underlying pigments that help to phosynthesise carbon dioxide and water to join together into simple sugars that can then be transformed into cellulose and other plant structures.
As the chlorophyll is absorbed, red phycobilins, yellow xanthophylls and orange carotenes are left in the leaves giving Autumn colours. This usually happens as the temperature cools and the plants start to store food and chemicals for winter.
I don’t know if these plants are doing thus? They remind me of the colours that are found in Swiss Chard.
