Miniature roses are true roses, bred to stay small in size. Most mini roses also have smaller flowers than standard rose bushes, but they come in a variety of types and colors. Miniatures also tend to be profuse repeat bloomers.
Despite their small size, miniature roses are extremely hardy. In fact, they are more winter hardy than most tea roses. The genetic parentage of miniature roses can be difficult to define since they have been in cultivation since the 17th century, but most originated as genetic mutations of Old Garden Roses (Rosa gallica and Rosa centifolia), or China roses (Rosa chinensis). Most types now grown are the result of extensive breeding and are quite divorced from the original native species. All miniature roses work well in a border or as edging. However, they are especially nice as specimen plants in containers, where they can be brought closer to eye level and truly be seen and appreciated. It could be invasive in North America.
