The Philip Island Hibiscus ("Hibiscus insularis") is a species of hibiscus that is endemic to Phillip Island, a small island to the south of Norfolk Island. The entire natural extent of this species is just two small clumps, and each clump apparently consists of multiple separate stems of a single genotype. It produces greenish-yellow flowers that fade to mauve through most of the year. Horticultural use of the Philip Island Hibiscus has greatly increased the number of plants (though not in its natural environment) but as it is usually propagated by cuttings the number of genotypes is still extremely small. This species is listed as Critically Endangered under Australian federal environment legislation.
