Wikipedia states that the term lawn dates to no earlier than the 16th century, and that in early 17th century Europe the concept of a closely cut lawn was born. I understand that certain luxuries were imported/exported and traveled great distances throughout this time period. Was grass seed ever considered one of these luxuries? If not, then when was grass seed first imported/exported (anywhere in the world) specifically for aesthetic reasons?
Note: Although I mentioned Europe in my question, I am not interested solely in Europe or the 16th-17th centuries for that matter. Perhaps, an example can be found even before this time period? Perhaps, it's only a recent concept?
