Lavender Cotton in early June

Santolina chamaecyparissus, commonly known as lavender cotton, is a species of flowering plant in the Asteraceae family, native to the western and central Mediterranean region. It is widely used in horticulture as an ornamental plant and has been introduced to various parts of the world for this purpose. The plant is recognized for its silver-grey foliage and yellow, button-like flowers that bloom in the summer.

Description

Santolina chamaecyparissus is a small, evergreen shrub that typically grows to a height of 20-50 cm. Its leaves are narrow, divided, and covered in a dense layer of silvery-grey tomentum, which gives the plant its distinctive color and common name. The flowers are small, globular, and bright yellow, appearing in dense clusters at the tops of the stems.

Cultivation and Uses

This species is valued in gardens and landscapes for its drought tolerance, low maintenance requirements, and attractive foliage and flowers. It is often used in rock gardens, as a groundcover, or in borders and herb gardens. Lavender cotton prefers full sun and well-drained soil and is resistant to most pests and diseases. It can be propagated by seed, cuttings, or division in the spring or autumn.

In addition to its ornamental use, Santolina chamaecyparissus has been used in traditional medicine and as an insect repellent. The plant contains essential oils that have been extracted and used for their antiseptic and anti-inflammatory properties.

Ecology

While Santolina chamaecyparissus is not considered invasive in most regions, it has the potential to spread in suitable climates, particularly in areas with Mediterranean-like conditions. It is important to monitor its growth and spread in non-native regions to prevent it from becoming a problem species.

Conservation

As a widely cultivated plant, Santolina chamaecyparissus does not face significant threats in the wild. However, conservation of its natural habitats in the Mediterranean is important for the preservation of this species and the broader biodiversity of the region.
