Q

What are some iguana-resistant plants?

I need to plant iguana-resistant plants in our garden in Puerto Rico. How or where can I find a list of plants disliked by iguanas? These animals are invasive in our gardens.

Answer

Iguanas are strict herbivores (eat plants only) so they may be attracted to your vegetable garden if you have one.

We do not have iguanas in New York, but I understand that they can be a big problem in gardens in semi-tropical and tropical areas such as Florida and Puerto Rico. As we are not experts on this problem, you might want to contact local experts such as

We were able to find some information on this topic. It is recommended that you try plants with thick leaves and stems. Strong-smelling herbs, such as rosemary and sage, are also good choices.  Some other recommendations are:

  • agaves and cacti
  • begonias
  • bromeliads - flowers may be eaten but not the leaves
  • bush alamanda (Alamanda schottii)
  • crown-of-thorns (Euophorbia milii)
  • Dracaena
  • glory flower (Eccremocarpus scaber) and glory bower (Chlerodendrum trichotomum)
  • Heliconia
  • jade plant (Crassula ovarta)
  • Lantanas (L. camaris)
  • Mexican sunflower (Tithonia rotundifolia)
  • oleander (Nerium oleander)
  • pentas or Egyptian star (P. lanceolata)
  • tropical gingers such as Alpinia purpurata or A. zerumbet

Note: See this discussion of iguana control by dogs.

  1. Bought 100 pentas, was told iguanas do not eat these. Well they ate everything. So, they had a great appetizer! Never seen so many in my yard before.
