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 patentissima, commonly known as Yellow Spreading Viooltjie, is a rare range restricted South African endemic perennial flowering geophyte found in the Western Cape’s Southern Cape Peninsula growing amongst fynbos in crevices in rocky north- and northeast-facing sandstone ledges. It is a dwarf plant growing from 8-13 cm tall with a solitary plain or spotted leaf, an erect green scape marked with purple blotches, a light green rachis, and a widely spreading perianth with bright yellow to greenish yellow flowers. This species blooms during spring.
