A rose is a subdivision of the larger category of flowering plants, which are defined by their ability to produce flowers. Therefore a rose is considered to be just one type of the many different kinds of flowers that occur all over the world.
Flowering plants are subdivided into two groups monocots (Liliopsida) and dicots (Magnoliopsida) that are based on whether the seed embryo produces one or two leaves, when it first sprouts. Roses are part of the dicot grouping.
The Rose Family
