Here are some recent photographs of two of my Pinguicula esseriana. Original plant obtained from Joe Griffin.
Pot: White plastic, 3 inch (7.5 cm) square x 4 inch (10 cm) tall
Media: 100% granular peat moss with a vertical layer of pumice through the center of the pot.
Water: Year-round, 1/2 - 1 inch (1.2 - 2.5 cm) in plastic tray.
Light: Year-round, 15 hours/day of "cool white" fluorescent lamps.
What do yours look like and how do you grow them?
