I saw this on another thread and thought it was worth posting again for others who haven't seen it yet. I know some folks here may not be able to view it if they don't have access to PBS from their cable company. But if you do have access and haven't seen it, do check it out! It's fascinating!

This documentary makes me believe that the invasive Brazilian Pepper Trees here in FL have that underground root network where the larger BP trees help their own seedlings to flourish. Fascinating experiments that these scientists have discovered. I think I missed my calling in life!
It also makes me appreciate fungi (mushrooms, etc) so much more now, too, for what they give to many of my other plants! Very cool!
