The wonderful wild bells!
Dim hidden copses
pooled with bluebells,
each frail but of deep hue,
bells gently waving,
(so unlike the Spanish
burly, sturdy, stand-up stiff and straight
garden ones – sad when they interbreed)
and sometimes mixed with milky white wood anemones,
or dazzling white stitchwort stars,
or warm red campion..
