The Agnata section of Pinguicula includes species such as agnata, gigantea, albida, and filifolia. The largest Pinguicula species, gigantea is found near Ayautla, in Oaxaca, Mexico on the steep slopes of Cerro Rabon. This species has glands on both sides of the leaves, which is unique among the Pinguciula world. I've seen mature plants almost a foot across online, but mine is still small yet already the largest Pinguicula in the collection. In winter, it doesn't seem to go truly dormant as it still makes normal sticky carnivorous leaves (although they are smaller in size). An easy growing plant for me, doing fine in peat, perlite, and vermiculite. I've yet to flower this species, but flowers appear similar to Alfred Lau #13. This species likes to be kept more moist than other Pings, so I've included a higher percentage of peat in the mix to help with this.
