Here is a recent photograph of my Pinguicula Yucca Do 1713 and 1717, original plants obtained from Travis Wyman.
Pot: Dark green plastic, 2 inch (5 cm) square
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.
I have not yet gotten mine to flower, though I understand that others have.
What do yours look like and how do you grow them?
