I rooted some around the October/November 2014 timeframe and grew them by windows/grow lights. Almost half of them have figs growing on them now but I don't think they will have time to ripen. If I had started about a month earlier (September), I might have been able to get more ripe figs this season. But it's my first year so I didn't try it.
If you don't want to grow them inside long, I would say about 1-2 months before your last frost would be a good time.
