Also, re: mistletoe
Yesterday I learned that not everyone knows mistletoe is a tree parasite. Which is interesting to me as a storyteller. In Norse mythology, the god Baldr is killed with mistletoe (thanks Loki...). His mother, Frigg extracted an oath from everything under the sun to not harm her child. But she skipped mistletoe because she didn't consider it a separate plant.
Taxonomy saves lives, people. :D
@TarkabarkaHolgy Other mistletoe trivia: there are some species that are epiparasitic, which is to say they are parasites of other species of mistletoe (which are parasites of trees).
