Common name: Viscid Jerusalem Sage. This species is native to the Middle East.

They are highly branched shrubs with a compact bearing and sticky touch that reach 1 meter (3.28 feet) in height. The leaves are dark green, lanceolate and have a rough and velvety texture. The intense yellow flowers appear in groups surrounding the stem. They bloom in spring and sometimes also in fall.

They are used to create hedges, shrub groups, borders and in rockeries.

Phlomis viscosa needs full sun exposure. It does not resist the salinity of the sea but it does resist frosts down to -10 ºC (14 ºF).

They grow in very limestone and stony soils, but they appreciate a well-drained substrate that contains a little organic matter.

They have high resistance to drought; water sporadically during the summer.

A light compost-based fertilizer will suffice in the second half of winter.

Prune in late winter to keep it compact.

They are resistant plants to the usual pests and diseases.

They are propagated from seeds sown in spring. These plants tend to self-propagate from the seeds they release.
