Miniature Roses: Most miniature roses have smaller flowers (less than 2 inches across) than standard rose bushes, but they come in the same variety of types and colors as their larger counterparts. Despite their petite size, 10 to 24 inches, miniature roses are extremely hardy. In fact, because they are propagated on their own roots (and not grafted onto the rootstock), they are more winter-hardy than most roses and tend to be profuse repeat bloomers. Miniature roses grow moderately quickly and work well in a border or as garden edging. They’re also especially nice as specimen plants in containers, where they can be brought closer to eye level and truly be seen and appreciated.
Miniflora Roses: Minifloras are a new kid in the rose garden as this classification was created by the American Rose Society in 1999. The miniflora class was developed for those rose bushes that grow too large in bush or bloom size to be classified as miniatures. The average miniflora rose bush size is 2 ½ to 4 ½ feet tall and can be within that range for plant width as well. The roses tend to be 2 ½ to 3 inches across offering hybrid tea-style and quick repeat bloom.
