These colors are often associated with moth pollination, and so some of the most fragrant Gladiolus can be found in this category. In this overview, white forms of usually colorful species are omitted.
Gladiolus robertsoniae F.Bolus is a summer rainfall species endemic to a small area in the highveld of southern Mpumalanga and the Free State South Africa where it grows in rocky sites, mostly dolerite outcrops, where corms are wedged in crevices and therefore protected from predators. Sites are restricted to areas that stay wet longer such as seeps or streambanks. Plants grow from 20 to 40 cm high. Plants flower at the end of the dry season (mostly October, but sometimes later). A species of section Hebea, it has large white long tubed flowers with fine red lines at the base of the lower tepals. Flowers are sometimes flushed light mauve on fading and are fragrant, scented of carnation day and night. Photo from Rachel Saunders.
Gladiolus wilsonii grows in the Eastern Cape which is a summer rainfall area, but is a winter growing species that is listed as flowering from October to November. It grows in open grassland in light loamy sand. It has short tubed white to cream fragrant flowers. Sometimes the reverse of the upper tepals is flushed pink to purple toward the tips and sometimes the lower three tepals have a short pale mauve streak near the base. The first two photos by Cameron McMaster. The last three photos were taken January 2010 for this species near Maclear in the Eastern Cape by Bob Rutemoeller and Mary Sue Ittner. Originally identified as Gladiolus inandensis which is very similar, it has now been identified as this species since the other species flowers July into August.
