As far as annuals and perennials go, everything did pretty well here for us in SW Michigan. Though it got pretty dry by the end of this summer!
As far as veggies go...I have limited space so I have to either do containers or shove veggies in between the plants around the house! I did a lot of snap peas, green beans, and squash. The snap peas (dwarf variety) surprised me by doing well and giving a nice crop (I thought I planted them too late in the season...guess not!). I want to try the snap peas in a container this year and see how that goes. I planted the green beans (bush variety) in containers and in the ground...the ones in the containers did REALLY well and produced for a long time. Squash did ok, but they were kinda squished together in the beds...need more room to do those. I tried lettuce and mesclun in containers...ehh, it was ok for baby lettuce, but they got buggy quick. We always do a cherry tomato in a big container, and of course that did great. I tried ground cherries too...cool plants and tasty fruits, but mine took FOREVER to get going this year and I only got a few good fruits before the frost hit...I'm not giving up on them yet, so we'll see what they do this year.
For those of you who don't have much space I highly recommend growing veggies in containers! So far, tomatoes, bush green beans, herbs, and peppers have done very well for me in pots. The yields seem to be higher and the plants seem to mature earlier than plants in the ground. You can move them around to get maximum light or move them to places (ex. a deck) where critters are less likely to get them. Harvesting is a cinch too!
Things I am going to try this coming year:
Carrots (in containers)
Ground Cherries (again)
Lemon Cucumbers (hopefully!)
What worked for you this year and what are you going to change/try out for the '09 season?
