Yellow may not be the first color that comes in mind thinking of Gladiolus, but there are some very striking species in this category. Quite often, there is a secondary yellow form of mainly orange or purple Gladiolus species.

Gladiolus woodii Baker grows in grassland, on rocky hillsides from 800 to 2000 m. in the summer rainfall area of South Africa from KwaZulu-Natal to the Limpopo Province. Mostly found in high elevation and high rainfall areas, it flowers early in the season, soon after it rains (from September to December). Leaves are often short and sheath the stem. Flowers are variable in color, pale yellow or lilac, oyster colored, dark maroon or red-brown with or without a longitudinal dark brown to purple stripe along the midline of the lower tepals and faintly to not scented. The upper tepals are much larger than the lower tepals and the lower laterals are folded. Photo from Rod Saunders.
