Kip beat me to it but I'll add to his comment. All offspring of the same two parents are the same grex. They would be siblings, but they would all be Gur. Barbara Kirsch. A batch of seedlings don't come out all the same, especially if we have different color forms of the parents. Crossing the standard forms will yield different results than crossing the alba forms of the same species. But they would all be the same grex if the same combo of parents are used.

Many times growers will assign clonal names or cultivar epithets to distinguish different forms of a cross. These would go in single quotes after the grex name. You might do some research to find which cultivar has the salmon color.
