We observed unusually low seed production in WNC native Panax quinquefolius
(ginseng) & Actaea racemosa (black cohosh) populations this summer from
forest interior habitats (mesic coves).  We did however observe seed
production in open & edge habitats with more light and propagated fields.
This may be explained by a lack of pollinator availability.
