I apologize Scott! I thought you were referring to a classification of roses, and I had never heard of a classification called "Native"!
Anyway, the roses that you are referring to as Native are, in fact classified as Species/Wild roses. Quoting Peter Harkness "Wild roses are also known as species roses. These ancient roses were native to many regions of the Northern Hemisphere."
To quote Charles and Brigid Quest-Ritson (Encyclopedia of Roses) "The ancestors of our garden roses are the wild roses from which all our cultivated varieties are descended. It is more correct to call them 'Rose Species' rather than 'Species Roses'. Wild roses occur all over the northern hemisphere."
Finally, to quote Liz Druitt (The Organic Rose Garden) "Species roses are the wild roses collected anywhere between the Arctic Circle and just above the Equator, the natural range for roses on this planet."
In regards to the specific roses you mentioned in your post, r. Virginiana is classified as Species/Wild, and was cultivated before 1640 by a breeder named Miller. It is native to North America.
R. Multiflora is also classified as Species/Wild, and began being bred around 1804. It is native to Japan.
R. Nitida is classified as Species/Wild, and began being bred around 1807, and is native to North America.
R. Canina is classified as Species/Wild, and began being bred in 1737 and is native in Europe.
So, I guess if you go by "Native" - I don't have any! But if you go by the classification - Species/Wild - I have one - big deal eh!
