It should grow well in the Ouachitas since they generally run east west, vs the Ozarks that run north south. Just need to find the right conditions, and learn associate plants (Paw paw, blood root, black cohosh, goldenseal...). If you can find black cohosh and goldenseal ginseng will be close by, if it hasn't been dug out.
