Pinguicula x ‘Weser’ 'Alba' is a carnivorous plant from the butterwort plant family (Lentibulariaceae). It is a hybridized plant and therefore grows nowhere in the wild. The plant produces a rosette of egg shaped to oval, bright green leaves. On the upper side of the leaves, there are many glands producing a sticky substance where insects could be caught with. The insects are digested on top of the leaves, the nutrients available are used by the plant. With enough light, it is possible for the leaves to turn a faint pink. Once per year, mostly in spring, one to several flower stalks are produces carrying a single white, spurred flower. Flowers are somewhat similar to the flower of a violet. Propagation is done by repotting the smaller rosettes forming near the base of the mature plant, or seeds.
