The Glowing Branches of Life .

After continuous winter rain, when all seems flattened and sodden, lichen glows almost unearthly in the gloom.

Lichen is an extraordinary composite creature made up of an algae or Cyanobacteria and a fungi living together in harmony. The algae can photosynthesis and make carbohydrates from the weakest sun and these feed the fungi, which in turn provides a protective home for the algae and a way to trap the water which they both need.

Lichen can grow on bare rock, on tree trunks on twigs and statues, it can grow in ancient forests and gravelly deserts and has even been taken into space and back with no ill effects.

There are 20,000 known species of this communal  creature, that does no harm at all to the medium on which it grows. It is not a plant and some growths of lichen  maybe the oldest living things on the planet.

After rain, the protective cortex becomes transparent and we can see the variously coloured algae layer underneath . This lichen was growing on the red twigs of dog wood blown down by the storm. On such dark winter days the lichen is positively luminescent and shades of tantalising green and orange flare out to remind us that the natural word is always  still alive and is still all around us!

    I love your gardens. You make them as real as if I were there. I so don’t have a green thumb, but I don’t need to because you do and bring your lovely, lush beauty into my world every time I read one of your posts!
