Hi,
please don't translate / transliterate the name of the architect and the garden into many language tags. These tags are only for cases of objects that actually have a name in these languages. 

OSM is also not the right place for long descriptions in 24 languages. These are in the scope of e.g. Wikipedia, but not of a map like OSM. Just adding the link to Wikipedia or Wikidata is sufficient and gives access to much more information than OSM could ever handle.
