These very distinctive roses are the result of crossing R. rugosa with garden roses. They form large, dense, often very thorny shrubs with plentiful, deeply veined leaves. The flowers are usually large, opening wide, varying from single to fully double. Many have delicious fragrances. Most of them repeat flower well later in the summer and some bear large hips at the same time. Few roses are so easily grown or are so free from disease. They are very winter hardy and grow well by the ocean.
