No, Catherine married into the Van der Salm family and hybridized for that company. That is my understanding. But my guess is, and it is just a guess... since these lilies appear in the cheapo catalogues I think the wholesale growing may have been transferred back to the Dutch. In fact, I am pretty sure I bought my American West from one of those catalogs.
I can't vouch to how good they are as American West is the only "American" that I have grown. I can say it has lasted longer than some lilies in my garden and grows under adverse conditions (in the rootzone of my neighbor's Western Red Cedar).
