Pinguicula rotundiflora

A small Mexican butterwort from the Sierra Madre Oriental of Nuevo León, where it grows on gypsum hillsides, shaded canyon walls and mossy rock in pine-oak woods at about 850–2,400 m. Like other Mexican butterworts it has a summer growing season with rain and a drier winter. It holds the RHS Award of Garden Merit and is easy to grow in a bright, frost-free spot.
