Unless you are a creationist but...
The difference in DNA content between say H minor and H.longipes
is about 10 picogram or 10.000.000.000 bases. Humans have in
total about 7 pg Do you really think that that amount of bases can
come along in a 1000 years, without changing the number of
chromosomes? Venusta separated from H. minor about 10.000
years ago and both still have about the same amount of DNA in
each nucleus. Based on that, my guess is that the japanese hosta
species separated from the korean Hosta species at least 100.000
and maybe even half a million years ago.
