For my peppers, the change in weather didn't just keep them alive, the change in weather made them THRIVE! We have cherry peppers, jalapenos (tons), banana peppers and bell peppers.
We started with seeds and only a few small plants. Two of the pepper plants (one from seeds, one from an over fertilized and almost dead plant) are now as tall or almost as tall as my bush.
Some other plants that hung on were our tomato plants - heirloom, beefsteak, cherry and grape. They are currently producing at a bare minimum and are limped over from the summer heat beating, but whether I get one more tomato off of them or not, I don't care because they gave me more than enough produce this season.
As far as the rest of our planting efforts... we grew beautiful sunflowers from seeds.
So what's next? Well, we're currently pickling our load of peppers.
And once this year's crop dies (because of the way-too-early cold front we're having), we'll take the winter off and plan to get a much better jump start on next year. I complained this summer that I was too young to have a garden and swore to not have one next year, but the pride of our success has just been too much to quit!
