Jerusalem sage is a shrub that produces delightful yellow flowers even in drought conditions and very poor soil. It is an excellent choice for arid climates and hard to plant problem sites.

The shrub is evergreen in USDA zones 8-11, though it can be treated as a perennial in zones 7, 6 and, sometimes, zone 5. The growth will die back with the frost and grow back from the roots in the spring.
