About Jerusalem sage
Phlomis fruticosa, also known as Jerusalem Sage, is an evergreen perennial shrub native to the Mediterranean region, valued for its velvety grey-green foliage and striking spikes of bright yellow flowers that appear in spring and summer. Its dense, rounded habit, coupled with its drought tolerance, makes it ideal for rock gardens, sunny borders, or as a low-maintenance plant in Mediterranean landscapes. It attracts pollinators and adds a rustic, vibrant touch.
Native range
Mediterranean region (Southern Europe and Middle East)
Care tips
It requires full sun for optimal flowering and healthy growth. It is very drought-tolerant once established, so watering should be sparse, allowing the substrate to dry completely between waterings to prevent waterlogging. It prefers well-drained soils, even poor or sandy ones; a universal potting mix with sand or perlite is suitable. Avoid overwatering, as it is the most common mistake and can lead to root rot.
