Beach naupaka (Scaevola taccada), an invasive pest plant, was discovered growing on the edge of a mosquito control dike at the Oslo Riverfront Conservation Area. Its large, somewhat waxy leaves are yellow-green. Fast-growing, this one plant was more than six feet across.
It also is know as half-flower …
Please do not confuse this invader with our native, beach dune plant, inkberry (Scaevola plumieri), which is is much smaller in stature, has dark green succulent leaves, and is listed as a threatened species. It is pictured below growing in Archie Carr National Wildlife Refuge ..
It, too, has a half-flower …
Inkberry only occurs on our beach dunes, while the invasive pest species colonizes the beach and elsewhere …
This invasive pest plant, pictured above in the dune at Archie Carr National Wildlife Refuge, still is for sale. Please do not plant it in your landscape.
Enjoy the Oslo Riverfront Conservation Area 
This Scaevola taccada Naupaka was quite large. The leaves themselves were up to 8″ long flowers small for this size plant. Was treated and will be revisited at another date by ORCA volunteers

Our HOA planted this Half-flower on our beach cross over! I am now in the process of removing it. I shared the information about invasives and had a good response.
