Personally, I don't see anything inconsistent about being grateful for something that wasn't a deliberate act. I can see at least two reasons for doing so: Part of expressing gratitude is for the benefit of the person expressing gratitude rather than for the person being thanked. Even if it wasn't a deliberate act, the person being thanked may appreciate knowing that they benefited someone. Although, this wouldn't apply to plants which aren't sentient.
