The rose, being the most popular garden and cut plant, has over 20,000 cultivars in the Northern Hemisphere alone. This number originates from a conservative figure of only 150-200 species of wild roses. Fossil specimens found in both Colorado and Oregon show that roses have been growing for more than 30 million years to date. More fossil specimens were found in North Africa and are said to be at least 4,000 years old. Variant wise, only five of the massive figures above cut as the most popular: the Hybrid Tea, Floribunda, Grandiflora, Climber, and Miniature roses.
Hybrid Tea roses were first cultivated in 1867 by a French nurseryman named Jean-Baptiste Guillot. He achieved the first Hybrid Tea by budding an old Chinese garden tea rose and a European rose. While it is not as fragrant as the other variants, it is safe to say that this rose is the most popular of all because of its wide selection of colors and its long stem that makes it ideal as a cut blossom.
The Floribundas can easily be distinguished from Hybrid Teas because of their dense clusters and big, simultaneous blossoms sitting on its truss. It was first cultivated in 1909, crossing a Polyantha and a Hybrid Tea. This variant is generally easier to maintain than its parents, making it ideal for parks and similar spaces.
