Phlomis bourgaei, the puckered gray-green Turkish phlomis,[2] is a species of flowering plant in the family Lamiaceae, native to East Aegean Islands to South West Turkey.[3][4]

The specific epithet bourgaei is a taxonomic patronym honouring the French botanical traveller Eugène Bourgeau (1813-1877), who collected in Anatolia, North Africa, and North America.

Description

Herbarium specimen of Phlomis bourgaei, collected by Eugène Bourgeau in 1860.

It is a shrub, evergreen, growing to 1 m (3 ft) tall by 80 cm (3 ft) wide. The foliage shows a pronounced seasonal dimorphism. In winter and spring, the large, gray-green leaves develop horizontally to maximize photosynthesis during the growing period. In summer, after the flowering, the big leaves fall and the plant then produces a new generation of smaller, undulated leaves, compressed against each other along the stems to reduce the area of sun exposure and limit evapotranspiration. These new leaves are covered with a thick coat of wooly, golden brown hairs.[5]

The flowers are yellow with 20–30 mm corolla, appear in April–May, and are carried in the leaf axils.[3]

In the wild, P. bourgaei grows in shrublands, oak scrubs, and pine woods, on serpentine and calcareous rocks.[6][4] In cultivation it requires a well-drained soil and an exposure with sun or partial shade, and tolerates limestone.[3]
