A hybrid tea rose that previously produced large pink blooms now shows only tiny wild-rose-like buds. What happened?
All hybrid teas are budded onto an understock (rootstock), which is often a wild rose species. When the grafted variety dies—typically from a harsh winter—the hardy understock takes over and begins growing from the root system.
If you keep this growth, it will become a large, once-blooming species rose with single flowers appearing only in spring. The original hybrid tea cannot be recovered once the rootstock dominates.
