Phlomis - Turkish Sage (Phlomis russeliana (Sims) Bentham) Russel's Sage Hardy Jerusalem Sage
Height 2 to 3 ft
Turkish Sage, is a striking and unusual species of flowering plant in the family Lamiaceae, and is native to Turkey and Syria; it is often confused with the closely related Phlomis samia, and is oftentimes wrongly marketed as Phlomis viscosa.
Commonly known as Hardy Jerusalem Sage and features fantastic whorled clusters of yellow hooded flowers on tall erect hairy stems and has interesting large heart shaped olive green leaves. Blooms early to the late summer. Winter foliage is very different - but equally striking! It produces the largest seed pods when well-watered throughout its blooming period in June, and reproduces at a moderate rate by way of runners which are quite thick and break off rather easily, which makes it easy to keep it from spreading and to propagate it.
Jerusalem Sage also contains an essential oil that has antibiotic properties that are effective against common food-borne bacteria, and has been used for centuries for food preservation. The plant is native to Turkey and Syria, but has been common in English Cottage style gardens since the 1900's.
