Campanula patula Spreading Bellflower RR DD N
Often Campanula patula in the British countryside is a merely a garden escape but here it is native. It appears in different places each year and gives the impression of being biennial or even annual. C patula seems to need some sort of ground disturbance to germinate and the seed appears to be long-lived. The leaves are mostly crowded at the bottom of the long stems and the flowers, although bell shaped on opening, soon spread wide giving rise to the English name: Spreading Bellflower.
It is mostly found around the Welsh border north of Gloucester with other records dotted about southern England but elsewhere it is rare and doesn't occur in Ireland.
