Why these two plants specifically
Iguanas gravitate to flowers and tender new growth, and hibiscus and bougainvillea deliver both in abundance. The blooms are soft, plentiful, brightly colored, and easy to reach at iguana height or up a low branch. To a grazing iguana they're close to an ideal food, which is why they're usually the first plants an owner notices being stripped.
The damage often appears overnight or over a couple of mornings — buds and open flowers gone, leaves chewed back to the stem, and a plant that looked full a week ago now sparse and ragged.
Why they're such a common complaint here
Both plants are staples of South Florida landscaping, planted along fences, pool decks, and entryways all over the county. That ubiquity is exactly why they generate so many of the calls we get about grazing. Replanting the same varieties in the same exposed spot without addressing the iguanas simply hands them a fresh meal.
What actually helps
Owners who want to keep these flowers usually layer a few measures together rather than fighting the grazing one plant at a time.
- Cage or net prized specimens while the resident iguanas are being removed
- Keep the showiest hibiscus and bougainvillea closer to the house, where there's more traffic and less cover
- Move tougher, less palatable plants into the most exposed beds by the water
- Collapse nearby burrows so the animals aren't denning right beside the buffet
Removal plus plant choice, not either alone
Plant selection nudges the odds but won't stop a hungry, established population, and no flowering plant is genuinely iguana-proof. Pairing smart plant placement with removing the resident animals and collapsing their burrows is what lets hibiscus and bougainvillea actually recover and hold their blooms.
Common questions
Will iguanas kill my hibiscus or bougainvillea?
Repeated grazing can weaken or even kill a plant, though many recover if the iguanas are removed and the plant is protected while it regrows. The key is stopping the daily browsing, not just cutting back the damage.
Are there flowers iguanas won't eat?
They tend to avoid tougher, more aromatic, or milky-sapped plants, but no plant is truly iguana-proof if they're hungry enough. Removal plus plant choice works far better than plant choice alone.
Why do the flowers disappear overnight?
Iguanas feed heavily in the morning sun, and soft blooms are quick, easy calories, so a plant can go from full to stripped in a single feeding session or two — which is why the loss so often looks sudden.
