Waterfall Gladiolus, Cardinal Red Sword Lily, Corn-Flag, New Year Lily, Superb Gladiolus, Hardy Gladiolus
Extremely ornamental, Gladiolus cardinalis (Waterfall Gladiolus) is a delicate-looking cormous perennial with gracefully arching stems bearing a spike of up to 12 brilliant scarlet red flowers in late spring to early summer. Each widely funnel-shaped flower, up to 3 in. long (8 cm), features striking white spear-shaped marks on the lower three petals. When seen in flowers in masses, the effect is truly brilliant. Forming a sturdy clump of upright, sword-shaped leaves, Waterfall Gladiolus is found growing on wet cliffs and waterfalls in the southwestern Cape area of South Africa where it is pollinated by the mountain pride butterfly.
