Certainly you can winter sow in the containers the plants will grow in. I'll paste in the FAQ for the technique. On that page do scroll down below "Tip" to find some links with growing tips, plant ideas, combo suggestions, etc.

Here is a link that might be useful: WinterSown Containter Gardening

Thanks for your reply Trudi and thanks for the link too! I look forward to the "fast forward" container making next winter...not that im wishing the time away....

It's a lot of fun to sow containers, you can go nuts with it ;-)

I had alot of extra seeds and had 1 container left that I just threw a bunch of seeds in. I'm not even sure what I tossed in there. I also stuck in a tuber from a mandevilla vine I saved last year. Not sure if that will come up or not but I figured with a 50/50 shot what can I loose? Lots of seedlings coming up now. I sowed them about 10 days ago & have been misting them nightly to keep them moist but not too wet.
