"Plants of Interest"

I think it is my turn to come up with a challenge. My idea is to do plants that are out of the ordinary...something you may not see every day or even maybe have never seen before. I was thinking more of a living plant but a plant that produces something such as a power plant would work also.

This one here is an okra plant. It is my first time seeing one. The okra grow "upside down"

This is an orchid that requires no soil just a humid atmosphere.

And Last: the largest power plant in the world!
