climbing roses are rooting with my other roses
Roses will not convert to a different variety. However, it's possible that your Sterling rose sent up a shoot from the below the graft union. The rootstock of hybrid tea roses is often a vigorously growing variety that could resemble a climber. Check the source of the long shoot. If it comes from below the graft union (or below ground) cut it off completely.
