Not aware if anyelse has tried this but in general the seeds from the jars have been in a vineger solution which, I believe, will render them useless, however in or close to the supermarket section that sells the peppadew are jars of peppaco peppers, these are very similar, if not the same as peppadews, but stuffed with soft cheese, these are not in vineger but in an oil solution so they may be viable? Anyway its my approach for next season.
