How do fairies tell the time? By the Town-hall clock plant of course.

The tiny cube-shaped flowers of the Town-hall clock plant, Adoxa moschetellina  resemble a miniature town-hall clock with a fifth facet on the top for any fairies flying overhead.

 These pictures were taken last Friday, 6th May 2016 in the woods on the north slope of Wolstonbury Hill and growing on the rotting stump of a dead tree probably from the 1987 hurricane.
It is found in damp woodlands.
