Latin name
Santolina chamaecyparissus
Common name
Silver Cotton Lavender
Type
Mediterranean aromatic perennial
Family
Asteraceae

Silver santolina is an aromatic and ornamental perennial plant highly valued for its fine, dissected, silvery-gray foliage, which brings a bright texture to sunny arrangements. Its compact and rounded habit makes it an excellent plant for borders, rockeries, herb gardens, patio pots, and Mediterranean-style flowerbeds. Its fragrant foliage creates a beautiful contrast with lavenders, sages, thymes, grasses, and flowering perennials with warm or purple colors.

Easy to grow, silver santolina prefers a full sun, warm, and well-ventilated location, in light, poor to moderately fertile, and very well-drained soil. It tolerates heat and dry conditions very well once established, making it an ideal plant for gardens requiring little watering. It does not tolerate excess humidity well, especially in heavy soil, and benefits from light pruning after flowering to maintain a dense, compact, and well-structured form.

Both decorative, fragrant, and useful for pollinators, silver santolina produces small yellow button-like flowers that add a bright touch to the garden. It is mainly cultivated for its evergreen or semi-evergreen silvery foliage depending on conditions, its characteristic fragrance, and its great drought resistance. It is an excellent plant for creating a dry garden, an aromatic border, or a natural arrangement with an elegant, durable, and easy-to-maintain style.
