Nomenclature

The specific epithet chamaecyparissus means "like Chamaecyparis" (ground cypress), though it is not closely related to that plant.[5] It is also not closely related to either cotton or lavender, despite its common name "cotton lavender".

Description

It is a small, evergreen shrub growing to 50 cm (20 in) tall and broad. Densely covered in aromatic, grey-green leaves, in summer it produces masses of yellow, button-like composite flowerheads, held on slender stems above the foliage. The disc florets are tubular and there are no ray florets.[6]

Cultivation

This plant is valued in cultivation as groundcover or as an edging plant for a hot, sunny, well-drained spot, though it may be short-lived. Once established, plants can tolerate dry and poor soils. Its compact shape can be maintained by cutting back in spring. [7]

Numerous cultivars have been produced, of which 'Nana', a dwarf form growing to 25 cm (10 in), has gained the Royal Horticultural Society's Award of Garden Merit.[8]

Uses

Cotton lavender has many potential uses. Most commonly, the flowers and leaves are made into a decoction used to expel intestinal parasites. An oil used in perfumery can also be extracted from the plant. Branches may be hung up in wardrobes to repel insects, and leaves are also suitable for use in pot pourri and in herbal tobacco substitutes.

In cosmetics it is used as a tonic.[9]
