Gladiolus natalensis, sometimes known as the parrot gladiolus is considered an heirloom plant for our area. This species can be left in the ground and grown as a perennial. Flowers of this species, which is native to Africa are a brilliant combination of yellowish green and red. The plant matures to about 4’ tall and blooms in late spring to early summer.
Glads may be used as background plants in the garden, or in rows, or as cut flowers for the home. These gladiolus may be grown as perennials, and usually increase in numbers each year. They are commercially available, however, only from specialty bulb sources. -Dr. William C. Welch
