| Spur on the rear of the flower sturdier that than on Common Butterwort. Stems grading green to browny-purple near the top, no stem leaves. Basal leaves are curled inwards, pale green, and like those of Common Butterwort have slippery hairs upon which insects come to their doom, before being dissolved into a soup that the plant can absorb as nutrient, for Butterworts are carnivorous. |

Easily mistaken for : Common Butterwort but that is shorter and the spur behind the flower that less stout. Hybridises with : Common Butterwort to produce Pinguicula × scullyi (Pinguicula grandiflora × vulgaris), but this hybrid is found in only one small part of southern Ireland, a much smaller area than what Great Butterwort occupies. No relation to : Butterbur or White Butterbur [plants with similar names]. Found mainly in the South West corner of Ireland. Likes moist or wet ground, bogs and acidic uplands.
