Plant Pick: Jerusalem Sage/Turkish Sage

Latin name:  Phlomis russeliana

by Vancouver Island Master Gardeners Association

Phlomis russeliana or Jerusalem Sage, a member of the mint family (Lamiaceae) is an attractive plant that appears deer resistant.

Its ovate leaves form a basal clump which remains green throughout the year, making it an attractive addition to a perennial bed even in winter. Starting in early summer, flower stalks grow to about 3 feet (90 cm). The whorls of hood-shaped yellow flowers encircling the stalks are long-lasting and suitable for cutting.

While preferring a sunny spot, this hardy herbaceous perennial easily tolerates some shade and is not fussy as to soil type.
