Simply amazing, part of the reason I keep reading here is that things I would never suspect just appear.<p>So knowing that people do come here and go elsewhere for cacti we can assume other types of plants are susceptible as well. Also based on this knowledge, is there any danger to purposefully spreading certain lines to other parts of the world? Surely there are similar environments which might become home to a transplanted variety, the danger is that its no invasive or dangerous to other specie.
