Latin name

Common name
Blue Santolina
Type
Aromatic Mediterranean perennial
Family
Asteraceae

Blue santolina is an aromatic and ornamental perennial plant prized for its finely cut, grey-blue to silvery foliage, which brings a very luminous texture to sunny arrangements. Its compact, rounded, and naturally structured habit makes it an excellent plant for borders, rockeries, patio pots, herb gardens, and Mediterranean-style flowerbeds. Its fragrant foliage creates a beautiful contrast with lavenders, thymes, salvias, rosemarys, grasses, and flowering perennials.

Easy to grow, blue santolina prefers a sunny, 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 low-water gardens. It does not tolerate excess humidity and heavy soils well, especially in cold weather. Light pruning after flowering helps maintain a dense, compact, and well-shaped plant.

Both decorative, fragrant, and hardy, blue santolina is primarily grown for its refined bluish foliage and its ease of maintenance in dry soil. Its yellow flowering in small buttons attracts pollinators and adds a luminous touch to the garden. It is an excellent plant for creating an aromatic border, a dry garden, or a natural arrangement with an elegant, durable, and Mediterranean style.
