Wild roses like R. carolina are native species that are genetically pure. Most modern hybrid roses, by contrast, are complicated creations, formed by a combination of selected crossbreeding between various wild species and their cultivars, as well as grafting techniques in which branches from highly ornamental roses are melded onto hardy wild rootstock from various native species. Wild roses, on the other hand, are known as "own-root" rose—their roots and canes are genetically the same plant. Wild roses are much less demanding than hybrid roses, though also less showy. Wild roses typically bloom just once, and their flowers are usually fairly simple single-petal blossoms, not the full double-petaled flowers that bloom repeatedly on a hybrid rose. Wild roses are preferred by native plant enthusiasts, while hybrid roses are for gardeners who like showy flowers for cutting.
