🦎 Iguana-Resistant Edibles: 
Community-Sourced Insights from South Florida Gardeners

If iguanas are eating your garden, you're not the only one. To find out what these reptiles truly don't like, I asked members of the South Florida Edible Gardening and Sustainable Living Facebook group for their experiences. They confirmed a common trend: iguanas have very specific tastes. 

A plant completely ruined in one garden might be ignored in another nearby. However, some clear patterns did appear that are worth looking into. 

If you’ve had a different experience with any of these plants, I’d love to hear about it.

Iguana-Resistant Plants 

Herbs 

Rosemary, basil (Thai and sweet), oregano, lemongrass, thyme, dill, parsley, garlic chives, society garlic, tarragon, Costa Rican mint, lemon balm, za’atar, catnip, elderberry

Roots and rhizomes

Turmeric, ginger

Leafy greens & vegetables

Everglades tomato, eggplant, arugula, radishes, misome, scarlet frill mustard, Jewels of Opar

Perennials & tropicals

Cuban oregano, Brazilian spinach (Sissoo), Okinawa spinach, longevity spinach (mixed reports), pigeon pea, Mexican sunflower, firebush, firespike, chaya (sometimes used as a “sacrificial” plant), black pepper, tarragon, avocado, bananas, pineapples, Barbados cherry (leaves and fruit)

Other reported deterrent or neutral plants
Macadamia nut tree, butterfly pea vine, miracle berry, fig leaves (usually avoided), coontie, bromeliads, ornamental grasses, Texas sage, aloe

💡 Note:  If you can get enough Chaya growing, you can use it as a sacrificial plant to protect your other crops. Iguanas love eating Chaya, so if you plant a lot of it, they are more likely to leave your other plants alone.

Mixed Reviews

These plants drew conflicting feedback — thriving in some gardens while becoming a salad bar in others:
Mexican sunflower, longevity spinach, Okinawa spinach, passionfruit, katuk, Sissoo spinach, milkweed, fig leaves

💡 Key Takeaways from the Community

• Local conditions matter. Iguanas near canals or waterways were more destructive than those in inland areas.
• Pets can be a deterrent. Dogs, and even feral cats, seemed to reduce iguana activity just through their presence and scent.
• Diversion planting works. Many gardeners, myself included, have found that giving iguanas an abundant favorite can help protect the rest of the garden. In my case, that plant is Chaya; they love it. I’ve planted it in many spots around the property, and since then, they’ve rarely eaten anything else.
