Primula frondosa var columnae

Perennial of the Primulaceae family, this entity — associated by some authors with Primula columnae as a distinct species — is native to southern Italy and the western Balkans, where it colonizes shaded limestone rocks and moist crevices at altitude.

It forms low and dense rosettes, remarkable for a green-gray foliage abundantly farinose on both sides, with oval, crinkled leaves, and crenate margins. This dense and uniform farinose coating, also visible on the stems and calyxes, gives the plant a very particular silvery appearance, more pronounced than in the typical form of Primula frondosa.

The flowers are a fairly bright pink-violet, with a well-defined yellow eye, gathered in abundant umbels on short stems. In its natural habitat, it blooms from April to June. In cultivation, it blooms from March-April.

It requires a well-drained, fresh limestone substrate, in partial shade, and proves to be relatively easy to cultivate among the primroses of the Farinosae section.
