The genus Santolina consists of about 15 species of evergreen shrubs native to the Mediterranean region. They are known for their aromatic, silvery-grey foliage and small, yellow flowers. Santolina is a popular choice for drought-tolerant landscaping and as a low-maintenance plant in hot, dry climates.
Region and Climate: Santolina is native to the Mediterranean region, but can be found in other parts of the world where the climate is hot and dry. They grow best in warm, dry climates with temperatures ranging from 60 to 85 degrees Fahrenheit.
Watering: Santolina is drought-tolerant and can survive with little water once established. However, they will benefit from occasional watering during extended periods of drought.
Soil type: Santolina prefers well-draining soils with low to moderate fertility. They can tolerate a wide range of soil types, including sandy, rocky, and poor soils.
Fertilizing: Santolina does not require regular fertilization, as too much fertilizer can result in excessive growth and reduced vigour. If necessary, a slow-release fertilizer can be applied once or twice a year.
Pruning: Santolina benefits from annual pruning to maintain its shape and size. Pruning should be done in the spring or early summer, after flowering.
Pests and Diseases: Santolina is generally pest and disease-free. However, they can be susceptible to root rot if the soil is too wet.
Propagation: Santolina can be propagated through seed, cuttings, or division. Seeds should be sown in the fall or early spring, and cuttings should be taken in the summer and rooted in a well-draining potting mix.
Landscape uses: Santolina is often used for low-maintenance landscaping, such as in rock gardens, borders, and as a ground cover. They are also commonly used in Mediterranean-style gardens and as an accent plant.
Cultivars: Santolina chamaecyparissus ‘Nana’ – A dwarf cultivar that reaches only 6-12 inches in height. Santolina virens – A species with bright green foliage and yellow flowers. Santolina rosmarinifolia – A species with needle-like, silvery foliage and yellow flowers.
