Obviously many others think so too. In my opinion there is something fishy with selling seeds at redicoulus prices just by calling them bonsai seeds. Many beginners are made to believe that they pay for a premium that is just not there. Since the bonsai seeds will grow exactly the same tree as normal seeds that is just a smart way to make more money without any gain for the unaware beginner. Actually many companies that sell bonsai marked seeds have no idea of correct storage, sprout rate or age of the seeds. Which means that seeds from reputable seed companies often is the premium shoice. Experienced bonsai artists dont by seeds marketed as bonsai seeds.
For beginners the best seeds is the ones you pick yourself locally.
