I have bought 'some' seeds on the LA this year (I just added a post to the thread LA sellers about them)
but you are right that I don't know whether they have sent the seeds from the crosses they offered..
I have germinated about 180 seeds so far and hopefully they will bloom next year.
But even then, can anybody say without a doubt whether a certain seedling is or isn't possible from 2 known parents?
The only way to know that is to make your own crosses and even than you have to keep good records of which pollen you used on which pod parent
