Shrub rose is not an official class of rose, but rather a way of grouping varieties that don't seem to "fit" anywhere else. These roses are generally very vigorous with an engaging, informal habit. Many modern shrub roses are also grown on their own roots, making them much hardier than grafted roses. They are better able to withstand harsh winter temperatures and can even come back from the roots after the top has completely died back. In the landscape, use them to create a stunning border or hedging, or as accents in the perennial garden. They will provide spectacular colour in the garden and blooms for bouquets with very little maintenance or attention.
