Yesterday, I removed a medium sized stand of beach naupaka about 60 feet from the ocean sea cliffs. What a chore! Some might ask why remove it? Three reasons:
- The local mongoose like to use it to hide out in. Not sure I want to give them shelter.
- It began to intrude on areas where it was unwanted (the neighborer's yard)
- A root fungus is turning it yellow and eventually it will die. Not a pretty picture!
Scaevola sericea is a native Hawaiian plant common to the shoreline and low mountains. The brilliant green foliage is quite beautiful next the contrasting black lava rock which makes up much of the shoreline on Hawaii Island.
There is an interesting Hawaiian folktale explaining why the white flower is only a "half" flower (pedals missing). Check out the story at Aloha-Hawaii.
Unfortunately, even this beautiful native can fall victim to disease! A soil born fungus will slowly wipe out that which once was healthy and beautiful! We first saw it in my neighbor's yard. He thought someone had sprayed his naupaka with Roundup! However, soils containing the fungus, Verticillium dahlia, effects the root system of many plants by blocking the uptake of water from the roots to the foliage. And our neighbor did import soils from the Hamakua coast to establish turf grass. The turf grass butts right up against an establish naupka bed. I suspect this is where the problem started. And it seems to be spreading!!! Although the process it slow, it isn't pretty!!!
