Pinguicula poldinii
A temperate butterwort described in 2001 and known only from a very small area of wet rock faces in Val d'Arzino, in the Friulian Pre-Alps of north-east Italy. It grows at about 450–550 m on cliffs that stay wet with seeping or dripping water, including rock exposed when the valley road was built. Treat it like the other European temperate butterworts: cool, constantly wet, bright conditions in summer, and a cold winter rest.
Where it grows wild
Steep rock faces kept wet by seeping or trickling water. Herbarium labels describe west-facing rocks beside the Tolmezzo–San Francesco road, and a field observation reports many plants on a dripping cliff. Much of the colony grows on rock faces opened by road construction. It is threatened by over-collection.
About 450–550 m, according to Wikipedia and herbarium labels (450 m and 510 m).
