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 vernus is a South African endemic species found in the KwaZulu-Natal, Limpopo and Mpumalanga provinces where it grows in rocky grassland in the Blyde River Canyon area. It flowers in in winter during the months of July and August in completely dry conditions before the first rain starts. Foliage leaves are produced afterwards in September or October. Flowers are pale to deep pink, or cream, with the upper tepals darker above and with a yellow zone on one or all of the three lower tepals. This zone is sometimes edged with dark pink or purple. The lower halves of the lower tepals are speckled with pink. Flowers are unscented and plants grow from 45 to 75 cm high.
