Alfred Lau #13 is an intriguing Mexican butterwort discovered in the wild by botanist Alfred Lau, renowned for his extensive fieldwork on Pinguicula species. Though its identity remains uncertain, it is suspected to be a form of P. gigantea or a natural hybrid involving it.

This plant features large, broad, and slightly wavy leaves that can span up to 8 inches across when fully mature. It grows rapidly and adapts well to year-round cultivation without a dry winter rest, provided the soil remains moist and lighting is bright. A vigorous and impressive specimen for growers seeking robust foliage and fast growth.
