LOL... Have you ever heard that changing one little thing can change a human into a frog - genetically speaking that is - well I think the same thing goes with spells... you might try spell check and see what you get when you use that one. However, you'll also need to figure in the phase of the moon, the positions of the planets at the time of your spell, the time of your birth and the time of the subjects birth. (not sure if with plants it's the time of first being a seed or when the seed was planted. Gods only know about clones and things like that...)
Good luck and ummm if the spell doesn't back fire or even if it does if you can still type with whatever appendages you end up with let us know the results.
