Hi Maureen,
Your last post was blank so I don't know if you found any help from the link Backyardgardener gave you.* Consider calling wildlife rescues in the state where you live.* You could do a google search with your state and use terms such as:
your state + wildlife sanctuary
your state _ wildlife rescue
Also consider contacting local zoos.

When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant.
