You don't get flowers without some other part of a plant.
Sometimes bulbs will push up a flower before the leaves appear, but flowers don't appear out of nowhere. A flower is the reproductive organ of angiosperms (flowering plants).
But in which way we could say from one flower to another, to refer to the flowers, which are not on the same plants, the ones stand alone? Because even if we say "one flower to another" it is still not be giving us the information that they are on different plants. While I'm saying this, in my mind, I have the image of a field that is full of different kind of flowers(and with the many of the same kind). How to say while I'm meaning to say;"from one daisy to a poppy " or "from one poppy to another" but without specifying, sticking strictly to the word "flower". This sounds really terrible when we say;from a flower which is on a plant to another flower which is on a different one(plant). So, I just can't see a way to break the vagueness that you pointed out.
Maybe, it saves us the trouble to say ;"The bee flies from flower to flower"
by regarding "from plant to plant" as redundant.
