In February 2013, out of curiosity, I tried to germinate some Black Mission seeds that I bought at a Trader Joe's (hence TJ). 3 seeds germinated and all grow happily! Please see 2 below.
They have been in the full SoCal sun since the day 1. For them, it either live or die, they must grow under the local sunny and dry conditions.
I have no idea if they ever produce any fruit and what it is going to be (I hope at least black), but if they do, how long would it take?
2 years, 3?
