I never tried planting something late in the year but I use to be able to keep my brussel sprouts going until late November early December with no problem. No one ate them but me at that time but I have one son who enjoys them now. I haven't done a full fledged garden in years. My grandson and I did some planting of tomatoes, green peppers, sweet potatoes and spinach last summer. I had an over abundance of tomatoes, a few green peppers but not much luck with sweet potatoes and spinach. The spinach actually fizzled out real fast.
