Re: TC and OS


Good question.

I suspect that the term Originator's Stock (OS) means whatever the catalog
writer wants it to mean.  I think generally the term is used to indicate
that the seller obtained the plant directly from, or can trace it directly
to the originator, indicating that there can be no question that the plant
is true to name.  At least that's what I've always assumed it meant.  Never
thought to ask.  I know that the 'Gold Standard' (along with many other
varieties) I sell did not come out of tissue culture, so if we go back far
enough through all the hands my initial plant passed through, it ultimately
came from Pauline Banyai's garden.  I guess I could theoretically call it
OS, but that would sure be a stretch.

The fact that a plant is not noted as (OS) does not mean that it comes from
tissue culture.
