Do Deer Eat Gladiolus? Everything You Need To Know

If you’re an avid gardener, you may have gladiolus in your outdoor plant collection. Gladiolus (also known as sword lilies)  are beautiful flowers that add a touch of elegance to any garden. But do deer eat gladiolus?

Deer do not usually eat gladiolus.  Gladiolus are deer-resistant because of their strong scent and bitter taste. But a hungry deer will eat almost anything, which may include gladiolus plants. 

Considering that a single deer can eat up to ten pounds of plants each day, you can see how deer eating gladiolus can really do some serious damage to your garden!

In this article, we’ll discuss how to stop deer from eating your gladiolus, and keep them healthy and beautiful all season long.

Why Do Deer Eat Gladiolus?

As we covered, deer usually stay away from gladiolus thanks to their strong scent and bitter taste.

Deer are most likely to eat gladiolus during spring because they’re hungry after a long winter, or if it’s late in fall and other food sources have been depleted.

Your gladiolus are less susceptible to deer damage later in summer when many other food sources they prefer are available.

Deer can do some serious damage to a large amount of gladiolus in a single sitting if they’re hungry enough!

This was confirmed in a 1999 study on deer plant eating habits by Cornell University.

And don’t think that your newer gladiolus are safer either: deer actually prefer new growth because they’re more tender.

Are Gladiolus Deer Resistant?

Gladiolus are regarded as deer resistant thanks to their taste and scent, both of which deer do not like.

They were rated as “seldom severely damaged” in a study on deer resistant plants by Rutgers University.

The bitter taste of the flowers and leaves usually keep deer away.

Deer have a keen sense of smell, and the strong scent of gladiolus also repels them.

As we mentioned earlier, just because gladiolus are deer resistant doesn’t mean they are completely safe from being eaten by deer.

You should always take additional steps to deter deer from your gladiolus and other plants and flowers.

Will My Gladiolus Grow Back After Deer Eat Them?

Fortunately, gladiolus can bounce back from browsing by deer if given some care, attention, and time.

Gladiolus are considered annual or perennial depending on which climate they’re in, so they’ll stay year-round or return each year depending on where you’re located.

Gladiolus grow from “corns”, not seeds, and they can be left underground year-round.

So unless a deer eats the gladiolus corn, you should see them regrow next year.
