If a dealer sold you green mixed with stratified seed or green as stratified they know and are purposely rippin you off! The two are totally different visually and by smell or any other test.
I find it hard to believe that suppliers would do this, there can be other reasons for your problems. Like using seed that has been stored over winter, instead of planting in the fall right out of the stratification box, you may get seed that will delay it's emergence. Tempature flucuation during stratification can cause this also. Maybe a poor site selection.
So it's best to know your stuff before pointing the stink finger.
You can trust my ginseng roots and seed though.
