'Phlomis purpurea' from the website Trees and Shrubs Online (treesandshrubsonline.
This species is closely allied to P. italica, but the floral bracts are broader, acuminate at the apex, and the teeth of the calyx sharply pointed. Also, the leaves are rather thinly coated with hairs on the upper surface. Native of S. Portugal and of southern and central Spain, common in the Ronda region. Bot. Mag., n.s., t. 518.
Introduced in the 17th century. Rather tender. In the wild it grows to a height of 3 or 4 ft, but in cultivation is usually of sprawling habit.
