Phlomis fruticosa, commonly known as Jerusalem Sage, is a bold Mediterranean shrub that brings texture, structure, and a unique flowering pattern into the landscape. It has a rugged, sun-loving character that fits perfectly into drought tolerant designs.

The foliage is one of its standout features. Soft, woolly, gray green leaves form a dense, rounded mass that gives the plant a muted, silvery tone. That texture helps it contrast nicely with glossier or finer-leaved plants.

In late spring through early summer, it produces bright yellow flowers arranged in tiered whorls along upright stems. This stacked flowering habit gives it a distinctive look that’s different from most shrubs and adds a strong architectural element.

It has a naturally bushy, somewhat informal growth habit, making it a great option for soft hedging, background planting, or filling out larger spaces with something that still feels structured.

Phlomis fruticosa grows best in full sun and requires well drained soil. It thrives in hot, dry conditions and is very well suited for low water landscapes.

It typically reaches about 4 to 6 feet tall and wide, forming a dense, rounded shrub. It is well suited for USDA zones 8 through 11. The foliage is evergreen to semi evergreen depending on climate.

This plant has low toxicity and is generally safe for gardens with pets and children.

The flowers attract pollinators such as bees.

It is generally deer resistant.

Phlomis fruticosa fits especially well into Mediterranean, coastal, and drought tolerant garden designs, where its texture and structure can be used to anchor a planting.

It pairs well with plants like Lavandula species to reinforce that silvery Mediterranean palette, Salvia clevelandii ‘Winifred Gilman’ for color and fragrance, and Ceanothus ‘Yankee Point’ to create a layered, cohesive drought tolerant planting.

Expert Tip:

I like using this as a structural filler in larger plantings. It doesn’t need to be the star, but it holds everything together. If you lightly shape it after flowering, it keeps a clean form while still feeling natural and relaxed.
