Here is a d20 chart of magical or otherwise useful plants for 4e. This is lifted directly from a spreadsheet a player in my campaign compiles and updates between sessions. All abbreviations and effects are as notated by him based on what I said at the table; as my notes are scattered and disorganized, his spreadsheet has more or less become a better resource than my original notes! For simplicities sake I have left out the unique effects created by combining different plants.
