[Tagging] semantic issue with "genus" in the wiki, wetland, plant nursery, ...

I'm interested in this topic in order to be able to map flowerbeds in a
rose garden. Besides the problem with the genus/species/taxon tagging, I
also need to be able to properly tag the flowerbeds themselves. There seems
to be quite some variants for that as well.
So I hope the outcome of this discussion is also applicable to flowerbeds.
