Name: Anne Summerville, SC (Zone 8a) Only dead fish go with the flow!
I have a copy of a Winter Sown Database compiled for zones 0 -10. It's in MS Excel form which can be opened with Open Office software. It's huge so I broke it up into two files, zones 0 - 5 and 6 - 10. It's list of results of various seeds winter sown .. it's pretty comprehensive for most common plants. Just click on the links and choose save.
Human beings, who are almost unique in having the ability to learn from the experience of others, are also remarkable for their apparent disinclination to do so.
