This is a bush about ten feet high, growing on the edge of Dartmoor. It’s rather thin, but bushing out a bit now, having been cleared around a bit. The flowers are below the leaf, turned upside down to photograph them and the leaves the right way up are in the second picture. It’s been where it is since before 1956. Perhaps with a bit more light reaching it it may flower a bit more and lower down in the future.
Nobody was able to say what this plant was, but we think it is Enkianthus campanulatus.
