(And maybe something about whether its edible or not, but I don't know how to phrase that, or specify to whom.) See a few articles that could benefit: Blueleaf, Bluecap, Duskwood (tree). Thoughts?
P.S. Note that some "plants" are considered creatures (Hangman tree), but I don't feel like that fits for most of them.
It's very possible it's been discussed before; I'll admit I don't really follow the forums. What I could find was the discussion Forum:Are plants considered items?, which is related in terms of categorization but didn't broach the idea of a plant template (according to my skimming). I would like a standardized template because I have big plans for a bunch of plants I would like to put in/clean up, you see :)
