Answer:

Classification Characteristics — No other flower has a wider range of size, color, shape and flower form than the rose for attractive and easy adaptation to any garden setting. Roses are among the most versatile of plants. They come in every shape, size and color imaginable with architectural dimensions, both in bloom and plant size, that make it possible to please everyone! They bloom constantly from early spring to late fall, providing a rich tapestry of color in the garden.  

Species Roses — Often referred to as “wild roses,” species roses are usually single-petaled (4-8 petals), once-blooming and have a bush size ranging from two2 to 20 feet. They are listed according to their Latin name, beginning with R. for Rosa and can have common synonyms. For example, R. foetida bicolor is also known as 'Austrian Copper'.  

Old Garden Roses — In 1966, the American Rose Society defined old garden roses as those types that existed prior to 1867, the year of introduction of the very first hybrid tea, 'La France'. Within this generic definition, a number of popular subdivisions exist based on natural historical developments and characteristics. The flower form can be quartered, cupped, imbricated or expanded, reflexed, globular or compact. After an initial spring crop of blooms, some varieties may produce no more flowers the rest of year, but their hip production does add a different kind of beauty to the garden.

Modern Roses

The era of modern roses was established in 1867 with the introduction of the first hybrid tea, 'La France', by the French breeder Guillot. This variety was considered unique for a number of important horticultural reasons. First, it possessed the general habit of a hybrid perpetual as well as the elegant shaped buds and free-flowering character of a tea rose. By the late 20th century, more than 10,000 hybrid teas had been bred with great success. The introduction of 'La France' heralded the era of modern roses. Breeders were quick to recognize that planned parenthood could evolve new flower forms, size, growth habit and colors. Therefore, the following new classifications based on growth habit evolved.

Hybrid Tea & Grandiflora — Perhaps the most popular class of modern roses is the hybrid tea, easily recognized by the large shapely blooms containing 30 to 50 petals. Flowers are borne on long stems either singly or with several sidebuds. In 1945, the 'Peace' rose heralded the modern era of the elegantly formed hybrid teas. So dramatic was the overwhelming public acceptance and praise accorded this variety that its place in history was instantaneous. Since 1945, many thousands of new hybrid teas have been bred and introduced.  

Floribunda & Polyantha — Second only to the hybrid tea and grandiflora in popularity, the floribunda is characterized by its profuse ability to bear flowers in large clusters or trusses with more than one bloom in flower at any one time. This class is unrivaled for providing massive, colorful, long-lasting garden displays. The distinct advantage of the floribunda is its ability to bloom continually whereas the hybrid tea exhibits a bloom cycle every six to seven weeks. Floribundas as a class are hardier, easier to care for and more reliable in wet weather than their hybrid tea counterparts.  

Polyanthas are generally smaller but sturdy plants with large clusters of small 1-inch diameter blooms often used for massing, edging and hedges.

Miniature & Miniflora — These classes have increased in popularity due to their novelty and versatility. They can be used for edging beds, growing in containers and rockeries or even for taking indoors as temporary pot plants for decoration. The height of the average plant is about 15 to 30 inches, and flower form and foliage are indeed miniature versions of both hybrid teas and floribundas.

Miniflora roses are a new classification adopted by the ARS in 1999 to recognize another step in the evolution of the rose, intermediate bloom size and foliage falling between miniatures and floribundas.

Shrub (Classic & Modern) — Shrubs are easily characterized by their sprawling habit. There are five popular subdivisions within the class: hybrid kordesii, hybrid moyesii, hybrid musk, hybrid rugosa and shrub. They can grow from 5 to 15 feet or more in every direction given the correct climate and growing conditions. Noted for their hardiness, they are usually vigorous and produce large quantities of clusters of flowers.
