Strange plants appearing in the rubble which passes for a path next to the shed. Scattered over maybe half a square metre. Each bubble like thing maybe two thirds of a centimetre in diameter. Maybe the result of being a spring, draining the back garden which slopes up as it goes back. How does one find out what they are? Upper left hand shot a close up of the lower right hand shot. Both done with telephone. Maybe I should have used FIL's Olympus for a higher grade botanical shot.
