Common questions about Gladiolus
- Is Gladiolus deer resistant?
- Gladiolus (Gladiolus sp.) is rated Seldom Severely Damaged on the Rutgers NJAES four-tier scale. Light browsing at worst; rarely ruined.
- What hardiness zones does Gladiolus grow in?
- Gladiolus is hardy in USDA zones 7 to 10. Outside that range it will either not survive winter or will struggle with summer heat. That is the range across the genus, so a named species or cultivar may be narrower.
- Does Gladiolus grow in shade?
- No. Gladiolus wants full sun and will grow thin and flop in shade.
- Is Gladiolus toxic to dogs or cats?
- Yes. The ASPCA lists Gladiolus as toxic to dogs, cats, and horses. Site it away from where animals graze, or choose something else if you have a dog that chews.
