Phlomis fruticosa, the Jerusalem sage, is a species of flowering plant in the family Lamiaceae, native to Albania, Croatia, Cyprus, Greece, Italy, Montenegro and Turkey. It is a small evergreen shrub, up to 1 m (3 ft) tall by 1.5 m (5 ft) wide. The sage-like, aromatic leaves are oval, 5–10 cm (2-4ins) long, wrinkled, grey-green with white undersides, and covered with fine hairs. Deep yellow, tubular flowers, 3 cm in length, grow in whorls of 20 in short spikes in summer.
