Gladiolus is the largest genus in the Iridaceae family with around 255 species. They are perennial bulbous flowering plants, sometimes called Sword lilies, but usually by its generic name, Gladiolus. It has been studied by taxonomists and now includes the genera Acidanthera, Homoglossum, Anomalesia and Oenostachys. The geographic range includes Africa, Madagascar, Europe, and the Middle East. They are treasured the world over for their beautiful, showy flowers which grow on tall spikes. These plants are often planted in cut flower gardens or in the back along the border, as they grow 60cm to 1.8 m tall. They make excellent cut flowers and are easily grown in raised garden beds and rockeries. Most Gladioli do equally well in pots. Gladioli are the flowers associated with a fortieth wedding anniversary.

Gladiolus inandensis, synonymously known as Gladiolus microphyllus, Gladiolus microsiphon, Gladiolus permeabilis var. wilsonii, Gladiolus stenophyllus and Tritonia teretifolia, is a South African endemic species found in the Eastern Cape and KwaZulu-Natal provinces. Gladiolus inandensis is a species that grows in small clumps to 20 to 45 cm. It is mostly found on sandstone soils in KwaZulu-Natal and the Eastern Cape. Plants are found on rocky grassland and flower early in the summer rainfall region, mostly July to August, extending into September. This species has small white to cream flowers flushed with purple on the outside of the tepals. The dorsal tepal is hooded over the stamens. This species is unusual in that the flowers are usually produced before the new leaves on short stems with the dry dead previous foliage leaves attached to their base. This species is very similar to Gladiolus wilsonii but that species produces a stem after the new leaves are produced and flowers at a different time.
