My new pitcher plant, S. purpurea ssp. purpurea f. heterophylla, is turning brown on the edges of the pitchers. The back side of them is turning slightly tan.
The pitchers were filled with rain water. It is planted in long fibered sphagnum moss just like Andrew grew it.
I've been worried about the heat generated on a cement porch with brick walls to the townehouse. Might a slightly cooler spot be better?
Why would this plant start turnning brown after only 4 days?
