Facts

Bird's-eye primrose is native to northeastern North America. In New England it is found only in Maine, where it primarily inhabits high-pH cliffs and ledges, and turf, mainly along the southeastern Atlantic coast. There is also a population on lake shore cliffs in central Maine, and it was formerly known from northern Maine on river shore cliffs.

2.  Primula laurentiana Fern. NC

bird’s-eye primrose. Primula farinosa L. var. macropoda Fern.; P. mistassinica Michx. var. macropoda (Fern.) Boivin • ME. High-pH cliffs and ledges, coastal ledges and turf. Primula laurentiana mainly along the downeast coast of ME (Washington County) on thin, often peaty, soil overlying bedrock usually in close proximity to the Atlantic Ocean. It also occurs at one site in central ME on lake shore cliffs and (formerly) in northern ME on river shore cliffs.
