West Virginia's ginseng digging season started Sunday and will continue through Nov. 30.
The herb grows wild in all 55 counties in West Virginia and last year its roots sold for an average of $508 per pound, according to the state Department of Commerce.
Plants are ready to harvest when their berries turn red. After a plant's roots are removed, state law requires that its seeds and berries be replanted in the spot where it was harvested.
Plants must be at least five years old to be harvested. Plants with three or more prongs are old enough to be harvested.
All roots must be sold to a registered dealer by March 31.
