Lavender cotton

Santolina villosa, commonly known as lavender cotton, is a perennial evergreen subshrub belonging to the Asteraceae family. It is highly valued for its aromatic foliage, which features a distinct silver-grey color and soft, woolly texture, providing a striking contrast in garden beds.

Native to the Mediterranean region, this species has evolved to thrive in harsh, sunny, and arid environments. Its natural habitat includes rocky slopes and dry grasslands, making it an excellent candidate for xeriscaping and sustainable garden projects where water conservation is prioritized.

Botanically, the plant develops a dense, rounded mound of finely divided, woolly leaves. During the summer, it produces bright yellow, button-like flower heads on slender stems. The entire plant is rich in essential oils, which give it a pungent, herbal scent often compared to wormwood or chamomile.

Agricultural requirements focus on providing excellent soil drainage and full sun exposure. In heavier soils, it is critical to amend the ground with sand or gravel to prevent root rot. Maintenance involves pruning after flowering to maintain a compact habit and prevent the woody base from becoming too leggy.

The primary uses of this plant are landscape design, borders, and aromatic hedging. It is also used in dried flower arrangements and traditional herbal medicine. While generally hardy, growers should be vigilant against root rot caused by poor drainage and pests such as aphids or spider mites, especially in confined or poorly ventilated conditions.
