It looks similar to those of labeled as Hibiscus rosa-sinensis 'El Capitolio' by western growers.

1. This is thought to be an intermediate form of H. schizopetalus that is linked to H. rosa-sinensis. It is an intermediate form that looks like a cross between Hibiscus rosa-sinensis and Hibiscus schizopetalus. The origin of this species is uncertain. Burkill, the English botanist says that it is a result of hybridisation between H. rosa-sinensis and H. schizopetalus. Another theory says that it is an extreme form of the ancient H. rosa-sinensis.
