It sounds like Fortuniana, was the grower from the SE
United States? Fortuniana is a common root stock for
growers in that area.

Growers select their root stock for the local conditions,
it is usually best to buy from a grower that has similar
soil & climate conditions as the area you will plant the
grafted rose.
