Acamadenia obtusata commonly known as Dune Buchu in English and Duineboegoe in Afrikaans forms a variable shrub, displaying floriferous pink flowers with aromatic foliage. Characteristic of the citrus family are oil glands found on the leaves, which release a fragrance unique to each species. Acmadenia obtusata is a single-stemmed, rounded or upright shrub, reaching a height of 0.3 to 1 m depending on locality and conditions. Leaves are evergreen, linear (needle-like), 10 to 11 x 1.3 to 1.7 mm, opposite. Oil glands are seen on the underside of the leaf, on either side of the midrib. Star-shaped, pink, solitary flowers are borne at the ends of short branchlets near the stem apices. Flowers are bright pink, 5-petalled, spreading, and 10 mm in diameter. Singular or groups of 3-5 flowers brighten up the bush during April to November, creating a buzz of activity by bees, insects and butterflies. The fruit is light green in colour and darkens as the capsule matures to release its seed. It forms a 5-chambered capsule bearing one black, shiny seed per chamber. Acamdenia obtusata can be used as a filler plant in a mixed fynbos bed; as a border or hedge plant by planting it in masses; or as a container plant. As cut flowers stems can be used in mixed floral displays.
