A real interesting but very difficult species in cultivation of the southeastern United States is Pinguicula ionantha. I grow this species now for 3 years and this winter my plant was flowering. I cultivate this species in a former aquarium, using as substrate 50% peat and 50% quartz sand. I also use living sphagnum moss between the plants to keep humidity high. In summer the plants are standing outside, 50% shaded, while in winter I keep the aquarium in my room, keeping the soil only moist to avoid any fungus attack. Winter temperatures are about 10-15 C. I have noticed that the plants began to produce its flowers at the end of winter due to a period of little higher temperatures and more wet soil conditions.
