A native Louisiana variety of indigo grew along the Mississippi River. The method
of processing the indigo was brought by the Bambara from the Senegal and
Gambia Rivers of Senegal and Mali. Here is a major indigoterie, indicated
by Alexandre de Batz on the plantation of J. B. Prévost
on the Mississippi at English Turn. Fort St. Leon was built adjacent,
one half by Villars du Breuil and one half by Jonathas Darby.
