Lachenalia, which belongs to the Hyacinthaceae family, is a genus of bulbous plants from southern Africa. The genus consists of nearly 130 species, most of which are quite short in stature with only a few exceeding 15cm. Many have large, eye-catching and ornamental flowers in an assortment of colours ranging from sea-green or blue to rich red and clear bright pink, often accompanied by attractively marked leaves. A handful of species are found in Namibia, but most are South African endemics with the greatest diversity found in the Western Cape. The genus name Lachenalia commemorates the Swiss botanist Prof. Werner de Lachenal (1739-1800) who was stationed at the University of Basel during the late 18th century. Propagation from seed is easy and straightforward and they are well suited to rockeries and being grown in pots.

Lachenalia mediana var rogersii is an endangered South African endemic species from the Western Cape Province. It grows from 20 cm to 40 cm tall with a single broad leaf with undulate to crisped margins. During spring it bears blue to pink flowers.
