I know that our club puts out flyers at the local places (not the big box stores) that sell plants. Try asking someone there if you do not see anything.
I tried Googling for things close to Binghamton NY and found these close:
The Binghamton Garden Club

Here is a link to other gardens:

Perhaps if you contact one of them you could get more information. Of course, you may have already tried that.
Hope that helps. Perhaps someone that lives closer to you can be of more assistance.
