Aaron, It sounds like you have found a patch. The first question I would have to ask you, as a grower, is if this is not growing on your land, how do you know that someone else hasn't planted it there for their own? Perhaps the property owner? If he/ she/ they have it growing there you are in effect stealing the sang. The last thing I could say on this is, how would you feel, if it was yours and, someone else helped themselves to it? If it is on your ground then it is yours.
As to the selling it, the best price will be for dried roots. There are some tips on here for that purpose, and it does take some effort and time. You will probably get a lot less for green roots but, you won't have the time and work involved in the process. The seeds may have good value of their own but, if you are removing the roots, the only way to preserve the sang patch, would be to replant the seed there where it is growing. The chemical that gives sang it's claim to fame is in the roots, seeds and leaves but, the root is what is sought after on the commercial market.
