Jealous Of My Neighbor's Garden?

Of course I am.  From one of the upstairs bedroom I can look right down on it and see the tomatoes that he (and his wife) are growing.  Am I jealous?  Of course I am!  Goodness knows that I have enough room for an outside garden but I have been busy with work and more specifically making my quota.

I have decided that I am NOT going to get upset but what I am going to do is work in my garden even if its just clearing the overgrowth away while I plan for next season.

Is there anything that can be planted so late in the year?
