Tungoil Tree Vernicia fordii

The seeds of Vernicia fordii are rich in unsaturated oils and are harvested to be used in the production of lacquers, varnishes, linoleum, oilcloth, resins, paints, greases, brake-linings, polishing compounds, and artificial leather.  Early in the 1900's, the importation of these oils reached millions of gallons per year.  Due to high demand for the oils, this tree was brought to the US by Gulf Coast farmers in search of cash crop. 

By the 1920's, there were over 10,000 acres of tungoil trees being grown along the Gulf Coast in Florida, Georgia, Alabama, Mississippi, Louisiana and Texas.  The 1940's come along, synthetic resins begin to become an alternative.  Production declined and it was no longer viable as a income producing crop.  The trees remained, and were able to establish themselves in disturbed habitats.  Its suckering habit has allowed it to flourish and spread.  In some locations it is considered an invasive and noxious weed.  

Controlling its growth and spread has proven to be a challenge. Since they can reproduce through suckers, removal of a tree must be complete.  After felling the tree, the remaining stump should be chemically treated immediately after the cutting is done.  

In its natural habitat, it can be found growing along right of ways, forest edges and in urban green spaces. 

(Flowers resemble Hibiscus syriacus).

Insects, Diseases, and Other Plant Problems:  Susceptible to dieback and canker.  

All parts of this tree are poisonous, consumption can cause death.  Its leaves can cause a rash similar to poison ivy.  

Spreading by suckers, it can become invasive.
