The American Spirit perique used to come from the late Percy Martin's farm in St. James Parish - I've read that from multiple sources but this is a five year old article that briefly discusses his son Ray's continued involvement with American Spirit and references Mark Ryan's purchase of LA Poche.

"In 2005, a North Carolina businessman named Mark Ryan bought an old
processing facility in nearby Convent, La., with a lineage going back to
Pierre Chenet, thought to be the first Westerner to produce perique.
Recently, he added to it. Mr. Ryan has more demand than he can fill with
his local farmers, and augments his barrels with tobacco from places
like Kentucky, Virginia and Canada, as his predecessor had done for
years as more and more farmers left the business.
Unlike Champagne or Cuban cigars, perique lacks a legal protection
defining where it must be grown or processed. But for the purist, the
only true perique is grown and processed in St. James."
The last sentence is a little misleading as none of us consumers know where our perique is coming from and I've seen various industry figures say that all perique on the pipe tobacco market is of the blended variety that has been grown elsewhere but processed in Louisiana. (Basically, what Cosmic said)
