As far as I'm concerned a verge or field edge, as in this photo, trumps any floral arrangement artificially created by human hand.
Or this. Zingy Knapweed and Orange Hawkweed. These are growing in the churchyard at Clun and are part of the God's Own Acre project. This initiative encourages the cultivation of wild spaces in burial grounds in order to allow the natural flora and fauna to flourish. These are not created by sprinkling packets of wildflower seeds, but are the species native to that region.
