Under currently Kentucky laws and regulations, you would not be able to sell the seed.
While Kentucky regulation does distinguish between wild, wild-simulated, and artificially propagated (woodsgrown and cultivated) ginseng - ginseng being defined under KRS 246.660 as \"American ginseng plant known as Panax quinquefolius,\" the harvest season is the same for all four \"types\" of ginseng.
kchacha is correct in terms of harvest meaning \"to take any part of the ginseng plant while the plant is living\" but if you look at 302 KAR 45:010 Section 4. Harvest, it says
(3) Seeds adhering to a plant taken during the season shall be planted within fifty (50) feet of the location of the plant with no tool used other than the finger.

Therefore, removing seeds from 50 feet of the mother plant is violation of Kentucky's ginseng regulation.
Until such time there is a way to establish a grower program and a way to enforce and implement a legal seed harvest that doesn't impact the wild seed, this is what we have to work with in Kentucky.
