Its interesting to see these plants as mere sprouts that LOOK harmless. Though not a follower of the poison path myself I'd be a tad weary of touching these.
They're an interesting plant. They'd be on my mind for a while and I happened across them rather randomly so I knew there was a message there for me. The energy of the Datura isn't inherently dark, in fact the ones I wildcrafted and the ones I am growing both have quite mild energies. I think it is likely in the application and use the darker aspects of the Datura spirit will emerge. I approach them with respect and love so we get along fine.
