Pinguicula potosiensis (P. moranensis)

Pinguicula potosiensis is a nomen nudum (an invalidly published name) that is taxonomically considered a synonym or a geographical variant of the highly variable Pinguicula moranensis. Endemic to the state of San Luis Potosí, Mexico, it is a heterophyllous butterwort that undergoes a distinct seasonal transformation. In summer, it forms a carnivorous rosette of broad, succulent, obovate leaves covered in mucilaginous glands, while in winter, it retreats into a tight, non-carnivorous succulent rosette to survive drier conditions.

It typically grows in temperate mountain habitats, clinging to damp limestone cliffs, mossy banks, or vertical rock faces within pine-oak forests. While it produces the iconic, long-spurred magenta flowers characteristic of the Moranensis complex, it is often distinguished in cultivation by its specific leaf margin habits and slightly more compact summer growth compared to other varieties. Because it is morphologically inseparable from the broader species, it is frequently grouped with Pinguicula moranensis or compared to Pinguicula rectifolia, which shares a similar cliff-dwelling habit and floral structure.

As always, plants can look different with different amounts of light. The plants you receive may be a slightly different color than what is shown, either more colorful or more green depending on a variety of factors. Plants are between 0.75-1.5" in size. All Pinguicula are shipped bare root. You may receive a plant in either its succulent state or in its carnivorous state regardless of the time of year. Plants in their succulent form can be up to 90% smaller in diameter than those in their carnivorous leaf form. Plants wrapped in paper towels and put into small deli cups, and shipped in an appropriate sized box. Heat packs are not included by default. We offer a 72 and 96 hour heat pack, and we only ship plants via USPS priority mail or priority mail express at this time.

 
I recommend growing them in an inorganic mix like equal parts akadama, pumice, and lava rock. I use the tray method during the spring, summer, and fall letting the tray dry out for 1-2 days before refilling it. In the winter I only refill the tray once every 10-14 days to allow them to go into their succulent state.
