A little background of roses

Roses have been around for a long time. People like to group, class and order things. Roses have been grouped and classified.
I have no desire to turn this blog into a huge lecture about classes and groups, but it is important to understand a few basics.
Roses can fit broadly into three groups. They are Species (wild) roses, Old Garden roses, and Modern roses.

Species

Old garden

Modern

The modern and old garden groups can be broken down into classes. Species can be broken down as well but for my purposes I am going to leave them under species.
Old Garden roses can be broken down into Gallicas, Albas, Mosses, Damaks, Portlands, Bourbons, Hybrid Perpetuals, Chinas, Teas, and Noisettes.
Modern roses can be broken down into Hybrid Teas, Floribundas, Grandifloras, Miniatures, and shrubs.
