Hibiscus insularis

This species, along with the rest of the island's vegetation, was under threat due to grazing by pigs, goats and rabbits. The removal of these feral animals has led to the regeneration of the population with seedlings surviving next to the original plants.

It has tiny, neat leaves and a densely branching form, making it a perfect garden plant. It is evergreen, disease-free and tolerates wind and full sunshine or partial shade. These characteristics make it a good hedging plant. 

This species is listed as Critically Endangered under Australian federal environment legislation.
