This is Gladiolus dalenii, also known as African Parrot Gladiola, and candy corn Gladiola. Previously known as Gladiolus natalensis, this plant is a large nectar source and is a great choice for attracting hummingbirds. The bloom is stunning and the birds, bees, and butterflies adore it. Gladiolus dalenii is also a great choice for use as a cut flower because the burst of color is breath taking. This tender perennial grows anywhere from 1 to 4 feet high and likes to live in the full sun. The brilliant red, orange, and bright yellow blossoms remind you that Spring is definitely here. Gladiolus dalenii is a larval host plant for the Iris Borer, and Spotted Straw Moths. USDA Hardiness Zones 8 to 11
