Over the years we've tried growing a few things on the balcony. Tomatoes (so-so luck),
lettuces (good success, but short season), etc.
The one thing we always seem to have roaring good luck with is peppers.
We're still eating the dried hot peppers from last year, so we didn't need any more of those.
This year we decided to try banana peppers, and as you can see
the results have been rather good (if we do say so ourselves)
