Karen --
I think I found your list, at least of what has germinated...
you wrote --None in platycodon, as always. This is year #5 and I've never had a sprout!
i've done them 3 yrs i think, at least 2, and I recall only 1 seedling. Surprisingly, it bloomed but it was very small. the plant i mean. I'll watch it this year... and so far, no germination this year either.
