Primula Bullatae section

These beautiful primulas inhabit limestone rocks in relatively dry areas of China, and so don't like too much water, particularly during the winter and early spring, although in the wild they are often open to the sky, and may be covered by snow in winter. They make clumps or cushions or mats of rather sticky leaves, which continue growing throughout the year, with the withered remains of dead leaves covering the extending stems indefinitely. The taxonomy is complicated, but it has been sorted out, so we now use the new names.
