I'm looking for a Pinguicula to grow in my Cephalotus pot. The soil is 1 part peat, 2 parts perlite, 1 part sand with a thin top-dressing of sphagnum moss.
The Cephalotus is on one side of the 4-inch pot, giving me 2.5 inches of open area. I would like to fill that open area with another carnivorous plant, specifically a Pinguicula (I have a sentimental attachment to Pinguicula).
To make a long question short, I need a small (less than 2-inches in diameter) butterwort that will grow year round in the same pot of Cephalotus.
