Pinguicula alpina only begins flowering after several years of growth.
Six to eight (occasionally up to 13) flowers are borne singly on unbranched inflorescences up to 12 cm (5 in) tall.
The zygomorphic flowers are 10–16 mm (⅜-⅝ in) long with a short yellow-green spur and are composed of a two-lobed upper lip and three-lobed lower lip.
They are white with one or sometimes three yellow markings on the lower lip.
These can be variable in size and shape.
The flowers are protogynous, meaning that the female stigmas mature before the male anthers, and are pollinated by flies.

Fertilized flowers mature into 6–9 mm (¼-⅜ in) by 2–3 mm (1/16-⅛ in) seed capsules bearing copious numbers of tiny, rust-brown seeds.
