Purple carrots have started sprouting. The sweet potato is trundling along. I've added some more purple carrots and some parsnips. Interestingly, the carrots where I left an inch of frond seem to have produced the largest fronds, where those that were cut to the quick (?) have sprouted in three or four places.
I do wonder if I'll get viable vegetables from these plants. I suspect they'll be somewhat mutated looking and probably best as seeding plants.
