The article started as a misplaced page, as it was added when hexxit alpha had thaumcraft which added silverwood trees. Strangely enough, even though thaumcraft isnt installed it is claimed natura has added its own silverwood tree, I looked through the entire page of code natura provides... I cant find anything about a silverwood tree. I know silverwood trees exist in hexxit because i've seen them and isolated one to perform some experiments to see if I could gather additional information, but I couldnt find anything... I simply added a picture of what i've found.
