OK, a few reasons for the question.
I wanted to open another thread for people to discuss and I thought it might be a fairly neutral thread to start and might be interesting.

I wanted an idea on how familiar you are with plants.

I wanted to ask which ones are your favourites, and your least favourites out of any you tried, and why.

I wanted to ask which plants the guide books lie about the most and which your personal experience reveals that the authors never did try the plant themselves.

I wanted to find out about any plants I don't know yet that somebody else might know about and have experience using.

The same thing for different uses of the plants, I bet some people have surprising information here.
After all, there are people posting on here from a wide range of places.

I am looking for any good web sites about plants you might know too.

I tried searching for the subject with the search bar and found plant uses in responses but not in a thread.

If you want to mention inedible and useless plants that is fine too.

Those are enough reasons for the question.
