there are 3 types of roses..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. http://cwf-fcf.org/en/resources/encyclopedias/flora/wild-roses.html 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'.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. The beauty of the old garden roses often lies in the heavy fragrance they can impart 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. here is great site https://www.rose.org/single-post/2018/06/11/Rose-Classifications
