More Information About Gladiolus
While commercial gladiolus breeding intentionally selects plants that will not be winter-hardy, we can thank our lucky stars that this was not the case in some of the early gladiolus hybrids. Additionally, many wild South African gladiolus species make superb drought-tolerant garden plants...perhaps not showy enough for a funeral spray, but nevertheless, great garden plants. I expect many of the gladiolus we sell will be much more winter-hardy than our Hardiness Zone ratings indicate.
Hardy gladiolus produce spikes of hummingbird-attracting flowers in a wide array of colors. Gladiolus love sunny spots in the garden, well drained soil and can tolerate dry weather. When happy, your hardy gladiolus will spread to form a nice colony of flowering plants. For a succession of bloom combine hardy gladiolus with peony, iris, agastache, and agapanthus.
