Phlomis viscosa, commonly known as Viscid Jerusalem Sage, is an evergreen shrub native to the Eastern Mediterranean, specifically found in rocky hillsides and scrubland. It typically grows to a height of 2-3 feet (0.6-0.9 meters) and a width of 4-5 feet (1.2-1.5 meters). The plant has a sticky texture due to glandular hairs, which gives it the name ’viscosa.’ It produces bright yellow, tubular flowers arranged in whorls along the stem, blooming in the spring and summer, which are quite showy and attract pollinators.

Viscid Jerusalem Sage is valued for its drought tolerance and the textural interest of its sticky foliage. It is often used in xeriscaping, Mediterranean gardens, and as a low-maintenance ornamental shrub in dry, sunny borders. It requires minimal water once established, preferring well-drained soils and thriving in full sun. While it is generally pest-free, it can occasionally suffer from root rot if overwatered or planted in poorly drained soils. This plant is not known for aggressive roots or significant disease problems.CC BY-SA 4.0
