Interactions with other Organisms 

Surprisingly enough the Hibiscus rosa-sinensis’ leaves provide a great home to a fungus called Phyllosticta discoreae, which has hyphal tips that grow on the ends of the dead leaves of the Hibiscus rosa-sinensis. The fungus Phyllosticta discoreae is currently being researched for its production of Taxol. The Taxol that is produced by the fungus Phyllosticta discoreae is the same Taxol that is found in the Pacific Yew Tree. This makes the Hibiscus rosa-sinensis the first angiosperm to have the fungus associated with Taxol produced on its leaves. However, there is still research currently being done on this, to help increase the production of the drug Taxol (since the fungus itself does not produce as much Taxol is the Pacific Yew). This mutualistic relationship is one that could end up potentially saving lives.

 This angiosperm is a primary producer in the ecosystem that it resides in. A primary producer provides energy for all other organisms in the ecosystem. The Hibiscus rosa-sinensis provides food for the Hibiscus beetle. This beetle eats the leaves of the Hibiscus rosa-sinensis. There are many other organisms that live in the same habitat as the Hibiscus rosa-sinensis. The Hibiscus rosa-sinenesis does not have any detrimental effects on humans. If anything the plants help beautify their yards and provide oxygen for them via photosynthesis.
