Primula bullata var. forrestii farinose form
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.
Primula bullata var. forrestii farinose form is a form of this attractive plant in which the winter leaves, persisting into spring, have farina on the upper surface, and thick farina underneath. This form is uncommon in the wild, but a seed-raised strain gives mainly farinose plants, from which we select the ones that do have farina. Otherwise it is like the usual form. New leaves, very sticky, grow each year on the thick stems, and old leaves can remain for years. The flowers, a cluster on the top of each upright stem, are a very bright yellow, with an even brighter centre, usually orange. It resents excessive winter wet, but can be grown outside if a sufficiently sheltered site can be contrived.
