We do not sell seeds. Seeds are the essence of what we do when we breed and if a person wants to be a breeder they need to produce their own seeds. It is a fact of life that you can acquire a flower and use it for breeding and you have obtained the many generations of breeding in the genes of that flower. You then need to add to it a set of genes from another flower(pollen) and that flower could also be one bred by the same breeder. You then get two sets of the genes from that breeder. However, if you get the seeds from that same breeder you are also getting his knowledge of what best crosses with what.
Or, you are getting some "bastard "seeds he did not want. One noted "breeder" sells seeds from random seedlings that grow in her seedling patch.
