Two Orange Welsh Poppy flowers (Meconopsis cambrica var. aurantiaca). One flower is has partly open petals so that the centre of the flower is visible. The other flower has the petals closed up and is bent over so that the side of the flower is visible.
Meconopsis cambrica is endemic to uploand areas of Western Europe, preferring damp, shady places on rocky ground. It is especially well adapted to colonising gaps and crevices in rocks and stones. This habit has enabled it to colonise the urban environment, growing between paving slabs and at the edges of walls.
