Pinguicula grandiflora

Large-flowered butterwort

Pinguicula grandiflora is a cold-temperate butterwort from western Europe, found in Ireland, Spain, France, Switzerland and the Jura, with a large purple to pink-violet flower up to about 4.5 cm across. It grows in wet, mossy seepages, stream banks and fens, and survives winter as a tight bud (hibernaculum). It is easy outdoors in a cool bog garden but must have a cold winter to survive.

Where it grows wild

Mossy, wet, often semi-shaded places: seepage slopes, spring fens, stream banks, wet rock faces and nutrient-poor wet meadows. Many sites are calcareous, though it grows on acidic peat in Ireland.

From near sea level in southwest Ireland to subalpine elevations in the Pyrenees, Alps and Jura.
