amberjewel said:Am I understanding correctly though that even if the seeds are black they may not be viable?
Yes. The black coating appears a few days after the pods are 19-20 days old - lets assume three to five days. That would mean that the coating turns black from day 22 to day 25. According to Arisumi and others, the seeds may not be mature/viable until after day 35. Therefore, even if the seeds are black they may not be viable if they are less than 35 days old (at typical summer temperatures for Maryland/Chicago/etc.).
It may be important to note that even though seeds at least 35 days old may germinate it is possible that fewer than the normal number (that would have germinated at 50-60 days old) will germinate.
