 The number of petals on a rose, determines the classification of the rose flower. The structure of a rose, known as the corolla, is made up of petals.

The petals around the rose, determine whether the rose is classified as a single, double, semi-double, or very double.

Before you choose a rose for your garden, you should consider the shapes of the flowers, along with the color, and size of the blooms.

A specific shaped rose might interest you more than another. You might want the ever-popular Hybrid Tea form flowers, or your interest might lean toward those lovely English roses. As you'll discover, the English roses have many flower shapes, from single petaled flowers, to some very full petaled beauties, and everything in-between!

Each rose,brings it's own unique beauty to the garden or the vase, so if you can't decide, plant a variety and enjoy them all!

 


How the Petals on a Rose, Determines its Classification

Rose flowers are classified by the number of petals on the bloom. Below is an explanation of the classification.

A single will have only one row of petals of the rose. There can be as few as 5 petals, from as many as 12.

A Semi double, has two or three rows of petals, and consists of 13 to 25 petals.

A Double, is a flower with more than 25 petals, and has three or more rows.

A Very Double,   includes many Old Garden roses, and David Austin roses with more than 60 petals.

A Full flower has 26-40 petals.

A Very Full rose, has more than 45-50 petals, in numerous rows.

A rose flower is considered Quartered when the petals open, in a way that, when viewed from above, it appears to be divided into quadrants.

Shapes of Petals on a Rose

The bloom shape of the rose is the way the petals are arranged on the flower. These shapes can range from flat, to globular, to quartered.

Most rose petals are flat and broad with little curling. Some flowers are re-flexed, (edges curl under). Some rose petals are frilled, or ruffled, and in interesting patterns.
