Aside from the brassicas, I've done bush and pole beans and short season cucumbers and gotten decent harvests before the frost kills them. I've also tried annual herbs like dill and cilantro but it was tough to get them to germinate in the heat.

Go to your MD extension service site and search for "fall vegetables." Mine in NC is http://www.ces.ncsu.edu/depts/hort/hil/hil-8001.html. It will tell you what types and varieties and dates and maturity dates. Including for Chinese cabbages, at least ours does.

I always grow my mints in pots because I am afraid to allow them the freedom of open ground. Every fall I sink them into a raised veggie bed and they always come back. I dug up some Cimicifuga in the fall because it wasn't doing well in an area that was not moist enough, I assume. We didn't get to replant before winter and they spent the entire winter above ground in a pot on the north side of a stockade fence and happily came back! Terrene...have you ever tried Lavender Lady? That is the only one that grows for me. I've had some for a long time and I wintersowed more in 2007 and not only did they come back, but the base of the stems was full of new growth very early this year. I am surprised, Linnea, if you have a problem with Sedum Purple Emperor. Mine came through the winter. In the past, I have left Autumn Joy outside all winter in pots near my front steps where water would drip into them and freeze into a solid block, then thaw and repeat and in the spring would fill with water for days before it thawed out completely. I was shocked that they survived this treatment year after year. I consider Sedum AJ to be indestructible...lol, and thought it applied to all sedums. Not sure about the PEmperor. pm2

I tried it on one row and pulled and replanted the other two. I wasnt impressed with the row I mowed, fert and watered. The rows I replanted I had a generous amount of beans. If you have at least 70 before a frost then plant a short dtm like contender. I always spray the frost off the beans to extend the harvest.
