Did you plant them too deep?

I don't believe so. I planted all the different varieties at about
the same depth, roughly about 1/8" deep. All the other varieties
germinated rather quickly. Just not a single Cherokee Purple, and
only one out of nine Sun Golds. Makes me think that there's something
funky with the seed I received.

I wonder if these seeds need some kind of scarification or other
pre-planting process in order to germinate?

Your seeds might need more light. Try the carrot seed trick. Germinate
between layers of damp paper toweling, then sow.

Thanks for the growing info. My seeds didn't come with much in the
way of planting information. I'll try sowing another round of seeds,
see if I have any better luck.
