Phlomis fruticosa, or Jerusalem sage, is an evergreen sub-shrub native to hot, dry countries in the Middle East and to some of the Mediterranean islands, including Malta and Sicily, so it will take any amount of baking. Growing to 4 feet (1.2 m) in height and perhaps 2 feet (60 cm) in width, theare massed with pairs of grey-green hairy , and the plant has a somewhat dusty look until midsummer, when its arresting bring it to life. These grow in whorls on the stalks, and are hooded, labiate and bright yellow. They flower in succession for about two months.
Phlomis fruticosa should prove hardy on a dry, sunny bank and looks best with plants of similar origin, such as verbas-cums, rock roses, lavender and thyme. Alternatively, it will do well against the south wall of a house, where Cotoneaster horizontal’^ could be planted behind to give a dark green background to the grey-leaved shrub. This cotoneaster, grown as a climber, will go to 9 feet (2.7 m), moulding itself neatly to the wall and needing no support.
