Lobostemon fruticosus is a small, rounded, woody shrub of a metre tall. It grows dense, hairy branches. The alternate, elliptic leaves are covered in soft, silvery hairs.
The flowers are several shades of blue or pink, paler towards the corolla lobes. There is a rare white flower form. The flowers are borne from late autumn until about midspring. The flower has a funnel-shape or a trumpet-shape; the stamens not protruding beyond the corolla tips. Flowers are mostly longer than 1,5 cm, up to 2,5 cm (Van Wyk and Gericke, 2000; Manning, 2009; Bean and Johns, 2005).
