The drop in temperature this week confirms that Autumn has definitely arrived. Crisp Autumn days can be absolutely gorgeous and the beauty of Autumn leaves always makes me feel… well, what? Nostalgic? Romantic? Sad? All of those things I suppose, but there’s also a peaceful, ‘snuggly’ feel and the promise of wood smoke and conkers and fireworks… and then Christmas – one of my favourite times of year!! And then the cycle starts all over again…
But why do leaves change colour so dramatically before they fall? Leaves contain chemical pigments, like chlorophyll, that makes leaves green and help in the process of photosynthesis. The leaves also contain the chemical carotene which has a yellow colouring.
Carotene is in the leaves all year, but is hidden by the green of the chlorophyll. As autumn approaches and temperatures, especially those at night, begin to drop sharply, the chlorophyll breaks down and reveals the other pigments within the leaf (such as the carotene) that aren’t affected by the cooler temperatures… and hey presto, the beautiful reds and golds we love start to appear.
Autumn leaves are very beautiful and a joy to press. If you don’t have the time or patience to press them conventionally, you can always try ironing them between sheets of blotting paper. Iron them on a low to medium setting and then get creative!
A friend of mine wanted to replace the glass panel in her Victorian-era front door. She couldn’t find any etched glass to her taste, so she pressed some leaves, bought two panels of glass to the correct size and ‘sandwiched’ the leaves in between sealing the sandwich with some clear silicon sealant, the sort you can buy in any hardware store.
Once dry, she put her ‘double glazed’ panel in place and careful tacked the beading back. The leaves have been replaced once over the years, I believe, as they do fade in the sunlight, but it’s an unusual idea and one that has earned a lot of compliments!
I’d love to hear your ideas for Autumn leaves. Do you press them or simply mulch them to put back into your garden? Quite often, I’ll collect the brightest, plus a few conkers and cob nuts and put them in a bowl on the table just to admire such lovely natural beauty…
