Selago canescens, in Afrikaans the blou aarbossie (little blue vein bush), is a shrub with many slender, erect stems. The blue in the common name refers to mauve flowers seen in late winter to early spring. The vein refers to the tendency of the shrub to “seek” out areas where underground water flows; probably leading to drilling projects on the free water divining information. Success rate unknown!
The stems of S. canescens are covered in small glossy green leaves, needle-like and soft. The abundant flowers are produced in dense clusters. The calyx is five-lobed. Small fruits ripen about a month after blooming is done. The distribution area of this plant is coastal slopes from the Cape Peninsula to the Eastern Cape.
Some sources place the Selago genus in a more restricted family, the Selaginaceae. Scrophulariaceae still seems to be correct though (Bond and Goldblatt, 1984; Gledhill, 1981; www.plantzafrica.com).
