As usual, take nothing at face value on this blog. This is Moschatel or 'Town Hall Clock' Adoxa moschatellina (so called because the flowers are arranged like the faces of a town hall clock, funnily enough)
This photo was taken in the south-east of Scotland by Stephen Longster but it is one of Northern Ireland's (and Ireland's) rarest plants - restricted to a few patches of woodland in the Cave Hill area above Belfast so worth a mention.
