The moderator of Crocus is sandnsea2 and she approved your proposal to delete that plant. It's best for a moderator to check the plant and make sure there are no images there before approving the proposal. If that check doesn't happen, then the images are deleted along with the plant, and that looks like it was the case here.
I'm sorry for the inconvenience, but if you could re-upload the photos again to the plant, that would be the only solution.
I also programmed the system to not allow the deletion of a plant if images exist.
