The Ultimate List of Common Plants Harmful to Rabbits

It can be surprising to learn just how many of our favorite garden staples are toxic to bunnies. Rabbits are often savvy enough to avoid plants that will make them sick, but a curious or very hungry rabbit (especially a young one) might take a dangerous nibble. Here’s a breakdown of common culprits to be aware of.

Toxic Bulbs Rabbits Should Never Eat

Spring-flowering bulbs are often the first meal for hungry rabbits after a long winter. Unfortunately, many of the most popular varieties contain powerful toxins.

  • Daffodils (Narcissus): All parts of the daffodil, especially the bulb, contain lycorine, an alkaloid that can cause severe gastrointestinal distress, drooling, and even heart issues.
  • Tulips (Tulipa): While rabbits famously love to eat the flowers and leaves, the bulbs are particularly concentrated with allergenic lactones that are toxic if ingested.
  • Hyacinths (Hyacinthus): Similar to tulips, hyacinth bulbs contain alkaloids that can cause intense irritation, drooling, and vomiting.
  • Alliums (Onion, Garlic, Chives): These plants contain compounds that can damage red blood cells in many animals, including rabbits, leading to weakness and anemia.

Poisonous Perennials and Shrubs

These garden mainstays form the backbone of many landscapes, but several popular choices are on the rabbit’s “no-fly” list for a good reason.

  • Foxglove (Digitalis): A classic cottage garden flower, foxglove is famously the source of the heart medication digitalin. It contains potent cardiac glycosides that are extremely dangerous to all animals if eaten.
  • Lily of the Valley (Convallaria majalis): Don’t let its sweet scent fool you. This delicate groundcover also contains cardiac glycosides and is highly toxic.
  • Rhododendrons and Azaleas (Rhododendron): All parts of these beautiful shrubs contain grayanotoxins, which can disrupt nerve and muscle function, leading to serious health problems.
  • Yew (Taxus): This common landscaping evergreen is highly toxic. The foliage and seeds contain taxine alkaloids, which can cause sudden death from heart failure with very little warning.
  • Hydrangea: These stunning shrubs contain cyanide-producing compounds, particularly in the leaves and flower buds. While a large quantity must be eaten, it’s still a risk.

Harmful Annuals to Be Aware Of

Even the temporary beauties we plant each year can pose a threat. Here are a few to handle with care.

  • Lantana: Its vibrant, multi-colored flowers are a staple in hot climates, but the leaves and unripe berries contain triterpenoids that can cause liver damage.
  • Geraniums (Pelargonium): While not deadly, geraniums can cause skin irritation and digestive upset for rabbits. They typically avoid them due to the strong scent.
  • Morning Glory (Ipomoea): The seeds of this beautiful vine contain a hallucinogenic compound similar to LSD, which can be toxic and disorienting for small animals.

Signs of Poisoning in Rabbits: What Gardeners Should Know

Whether it’s a domestic pet or a wild visitor, being able to recognize the signs of poisoning is a crucial part of responsible gardening. If you see a rabbit exhibiting these symptoms, especially near known toxic plants, it’s a cause for concern.

Keep an eye out for:

  1. Lethargy or Weakness: The animal may be unusually still, unable to move properly, or seem very tired.
  2. Loss of Appetite: A rabbit that refuses to eat is almost always a sign that something is wrong.
  3. Digestive Upset: Look for signs of diarrhea, painful bloating, or an absence of fecal pellets.
  4. Drooling or Foaming at the Mouth: This can indicate irritation from a toxic plant.
  5. Seizures or Tremors: A very serious sign of neurological distress.

If you suspect your pet rabbit has ingested a toxic plant, contact your veterinarian immediately. For wild rabbits, you can contact a local wildlife rehabilitation center for advice. They can tell you if intervention is necessary or possible.

Creating a Rabbit-Resistant Garden: Best Practices & Tips

Knowledge is power! Now that you know which plants are problematic, you can use that information to build a garden that’s less tempting. This is the core of our plants harmful to rabbits best practices.

Strategic Planting: Using Their Dislikes Against Them

Rabbits rely heavily on their sense of smell and taste to decide what’s on the menu. You can use this to your advantage!

  • Go for Fragrance: Rabbits tend to dislike plants with very strong scents. Think lavender, rosemary, sage, and mint. Planting these around more tempting targets can sometimes confuse their senses.
  • Choose Fuzzy or Spiky Textures: Plants with fuzzy leaves (like Lamb’s Ear) or prickly foliage (like globe thistle) are texturally unappealing for rabbits to chew on.
  • Plant “Rabbit-Resistant” Varieties: Many beautiful plants are rarely bothered by rabbits. Some favorites include Bleeding Hearts, Peonies, Astilbe, and Coneflowers (Echinacea).

Physical Barriers: The Most Effective Method

Honestly, the most surefire way to protect a prized plant is with a physical barrier. A simple chicken wire fence, at least 2 feet high and buried 6 inches deep to prevent digging, is incredibly effective for a vegetable patch or a bed of young, tender plants.

For individual shrubs or new plantings, a small wire cloche or tree guard can provide protection until the plant is mature and less appealing.

Sustainable and Eco-Friendly Rabbit Deterrence

Creating a rabbit-proof garden doesn’t mean waging war on wildlife. There are many eco-friendly plants harmful to rabbits strategies that work with nature, not against it. The goal is to create a balanced ecosystem where rabbits are encouraged to look elsewhere for food.

One of the most sustainable plants harmful to rabbits approaches is habitat modification. Rabbits are prey animals and love to have cover near their food source. By trimming low-hanging branches and clearing brush piles near your prized flower beds, you make the area feel more exposed and less safe for them.

You can also try companion planting. Interspersing fragrant herbs like oregano and marigolds among your vegetables can help mask the scent of more delicious plants, acting as a natural, living repellent that adds beauty and biodiversity to your garden.

Frequently Asked Questions About Plants Harmful to Rabbits

Are all parts of a toxic plant harmful to rabbits?

Not always, but it’s best to assume they are. For example, in a daffodil, the bulb is the most toxic part, but the leaves and flowers are still poisonous. With rhubarb, the leaves are highly toxic, but the stalks are edible. Given the risk, it’s safer to treat the entire plant as a danger zone.

My rabbit ate a small piece of a potentially toxic plant. What should I do?

First, don’t panic. Try to identify the plant and how much was eaten. Immediately remove any remaining plant material from your rabbit’s reach. Then, call your veterinarian or the ASPCA Animal Poison Control Center right away. They can give you the most accurate advice for your specific situation.

What are some beautiful flowers that are actually SAFE for rabbits?

Great question! You can absolutely have a gorgeous garden that’s also bunny-friendly. Some excellent, non-toxic choices include roses, sunflowers, zinnias, snapdragons, and pansies. Rabbits might still nibble them for fun, but they won’t be harmed by them!

Do natural rabbit repellents, like cayenne pepper spray, actually work?

They can work, but they have major drawbacks. Spicy sprays or predator scents need to be reapplied after every rain or watering, which can be a lot of work. They can also sometimes harm beneficial insects. A physical barrier or choosing naturally resistant plants is often a more effective and sustainable long-term solution.
