Description

Dianthus caespitosus is a spreading or tufted herbaceous perennial reaching 40 cm high, with linear (60mm x 5mm) blue-grey leaves along the stems (leaves usually deciduous or absent below crowns).

The inflorescence is simple (sometimes sparsely branched). It rises c. 20 cm above the main leaf tufts, with smaller (5-15mm) leaf-pairs dispersed along it.

The flowers are pale-yellow to cream coloured, c. 25 mm wide, and appear in Spring-Summer (Sept-Jan.). The petals (c. 15x20mm) are always somewhat toothed or fringed.

The calyx is elongated, 40-70 mm in length, with 3-4 bract-pairs. The calyx bracts are elongated acuminate, with sharp points, and only sometimes with faint, narrow papery margins.[3][4]
