We have been deep in drought for some years, but in just the last few weeks we have had enough rain to encourage small patches of green to peep through, and suddenly there are beautiful verdant mounds of moss appearing in nooks and cracks in the pavement, and around trees in the gardens. I’m beginning to think I might be able to experiment with this recipe from Stories in Space for getting moss to grow in specific areas:

Recipe:
(serves to create several small pieces or 1 large piece of graffiti)
1 can beer,
1/2 teaspoon sugar
several clumps garden moss
Plastic container with lid, blender, paintbrush

‘To begin the recipe, first of all gather together several clumps of moss (moss can usually be found in
moist, shady places) and crumble them into a blender. Then add the beer and sugar and blend just long enough to create a smooth, creamy consistency. Now pour the mixture into a plastic container.
Find a suitable damp and shady wall on to which you can apply your moss milkshake. Paint your chosen design onto the wall (either free-hand or using a stencil). If possible try to return to the area over thefollowing weeks to ensure that the mixture is kept moist. Soon the bits of blended moss should begin to re-couperate into a whole rooted plant – maintaining your chosen design before eventually colonising
the whole area.’

I love the other images and ideas at Stories in Space, in particular Myrmidon Castle (pictured above), and Hideaway.
