So I'm in the process of going through many of these and more plants looking for interesting specimens for my region. Its a lot of work but an interesting endeavor with lots to learn about.
I was wondering if someone can help me out a bit and scan through and see if you notice any worth while plants that I can focus on.
I'm sure a lot of you have a more extensive plant vocabulary than I do so it would be a HUGE help!

Thanks so much!
