General Rose Rootstock and Hardiness
Roses that are grown on their own root are able to come back from their roots even after winter damage has occured. Budded varieties are grafted on a rootstock that is different from the rose cultivar. Therefore, the original rose will not be what grows back from the roots if severe winter damage occurs. Budded varietes may require winter protection such as mulching the canes and crown with leaves or bark.
General Shrub Rose Description
Shrub roses bloom with numerous flowers along the stems. They are widely used in the lanscape for their own root hardiness, long blooming time, and carefree nature. Many have proven disease resistance. They perform well in masses or can be used where a flowering shrub is desired.
