The Structure of Rose Plants


Rose plants are a part of country gardens, and urban landscapes. Knowing the structure of a rose plant enables the gardener to better understand the growth habits, planting requirements, and pruning requirements/instructions for the various species of rose plants.


A rose plant's structure (from the bottom up) consists of the anchor roots, shank, bud union, canes and budeyes.

Root System

A good root system is necessary for the plant to grow, as the roots carry water and nutrients to the plant. Older (mature) rose plants will have developed a large root system.


The shank of the rose plant is part of the root stock, and it is from the shank that the bud union is formed. The shank and the roots support the above-ground structure of the rose plant.

Bud Union

The bud union is formed at the top of the shank, and it is bulbous in shape. It is an important part of the rose plant, as the canes grow from the bud union.


Canes grow upward from the bud union, and it is from the canes that leaves and roses are produced.


Budeyes are located in close proximity to where the leaves are attached to the canes. The budeyes are the sites that will produce new canes.
