I am sorry for this delayed reply to your gardening question. We are transitioning to a new Q&A system and your question was unfortunately lost in the transition. I have discovered it now and hope this reply is not too late to be of help.
I can't think of anything for your zone that is that narrow and short. I suggest you contact your County Extension Office for a list of plants that are adapted to your local area. Perhaps they are aware of some options that would work.
Thanks for the question. Please stop in again soon!
