The lineage is off a little. The US Patent states its the product of a Red HT x Lavender HT, and that the product is a Rose-Red HT. It reads a little weird, but its slightly more clear as you read further down.
We've added Roseland (in North Carolina) to the list of suppliers but note for the future, you can search for part of a name. In this case using the name contains option and searching for "Roseland" would have listed this nursery for you.
Please let us know what you find out so we can update the site accordingly, as it seems we may have this rose listed for Roseland in error now. We await your response.
