Hibiscus insularis is naturally found growing in Phillip Island which is a part of the Norfolk Island group on the east coast of Australia. 

It prefers well drained moist sandy soils in a open to protected sunny position and is drought and frost tender but salt tolerant. 

The Phillip Island Hibiscus is a rare shrub that is cultivated in gardens as a specimen or used in borders for screening. It may also be clipped to form a hedge or grown in a container and establishes in 2 to 3 years. It is grown in seaside gardens or used in tropical settings but is almost extinct in its native habitat. ID 1350
