A compact evergreen shrub with silvery, finely divided foliage and small button-like yellow flowers. Highly drought-tolerant and excellent for Mediterranean gardens, borders, and containers.

Why grow it

Santolina chamaecyparissus offers finer, more silvery foliage than many Mediterranean shrubs of similar size, making it particularly useful where textural contrast is desired in dry borders. It tolerates poor, well-drained soils where many ornamentals struggle, and its compact habit (typically 60 cm tall) suits smaller spaces and container cultivation better than larger alternatives like rosemary or santolina virens. The button-like flowers attract pollinators and support integrated pest management in perennial plantings.

Watch out for

Plants may become woody and sparse in the center after several years, requiring occasional hard pruning to maintain density, though recovery can be slow. In humid climates or poorly drained soils, root rot becomes a significant risk despite drought tolerance in ideal conditions. The foliage can bleach or fade if grown in deep shade, diminishing the ornamental appeal that makes the species worth cultivating.
