Nurseries grow an understock for two years and then graft or bud a variety of rose like a hybrid tea onto it. This is done by making a tee type cut low down in the understock, taking a budeye from the tea rose and inserting it into the cut. This is covered to protect it and keep it clean. The little "bud" then starts to grow and become the top of the rose bush. The next spring the canes of the rootstock are cut away and the grafted rose or "scion" takes over. It is allowed to grow for two seasons and then it is dug up for sale in the fall.
