Everything? Even water? And salt?
Then again, they are the only two consunables I can think of that haven't come from a living thing.
But I really don't think plants have any mental abilities. For one thing they have no brain, no ganglia and no nervous system. Their ability to sense stimuli such as light and water and their ability to react by growing towards them are achieved chamically rather than electrically, and any plant that does move itself (venus flytraps, for instance) do so by unavoidable mechanism, not decision.
But then again, it's entirely possible that their exists a soul that can exist despite the limits of the physical world. I just don't believe it.
And rocks being capable of thought is just silly.
