It is indigenous to the Northern Cape and Western Cape Province, South Africa, where it occurs on sandstone slopes, from the Cederberg in the north, eastwards to the Swartberg mountains, and southwards to the Du Toitskloof mountains and Swellendam area.[2]

Description

Dianthus bolusii is a tufted perennial reaching 40 cm, with linear (max.200mm x 3mm) blue-grey leaves, densely clumped near to the ground.[3]

The inflorescence is usually branched (1-8 flowers per stem), and rises c. 20 cm above the main leaf tufts. The flowers are white to purple, and appear in Spring-Summer (Sept-Feb.). The petals are very deeply fringed, lacerate or fimbriate (and sometimes strongly downcurved/drooping).[4]

The calyx is 23-27 mm in length, with 2-6 bract-pairs. The bracts have narrow papery margins and reach c. 1/3 up the length of the calyx.[5]
