Can a Shrub Rose Climb?
When it comes to roses, the term 'climbing' can be a bit misleading. By definition, a shrub rose is bred to stay relatively low, typically not growing more than 3 feet tall or so. However, the question of whether a shrub rose can be trained or supported to climb a trellis necessitates a nuanced answer. Let's explore this topic in more detail.
The Nature of Shrub Roses
Shrub roses are bred for their lower growth habit, making them ideal for borders, hedges, or formal gardens. These roses, such as 'Pollegre' or 'Blimplun', are known for their charming, compact forms. Rosarians spend years developing these varieties to ensure they remain a delightful size without the need for extensive pruning or support structures.
Do Shrub Roses Grow Canes Long Enough to be Trellised?
The answer to your question is typically no. Shrub roses are not bred to produce the long, strong canes that are necessary for climbing. Unlike true climbing roses, which have evolved specific structures like suckers and hooked thorns to support their lengthy growth, shrub roses focus on branching lower on the plant.
However, there are exceptions. Some shrub roses such as 'Etoile du Night' and 'Sombre Desir' do produce canes that can be trained to climb a trellis, but they do so in a more limited and controlled manner. These roses are often referred to as 'semi-climbing' or 'rambling roses' and may require some creative training to achieve the desired effect.
Training Shrub Roses as Climbers
If you still wish to train a shrub rose to climb, it is possible, but it requires some effort. Unlike a true climbing rose, which has its own mechanisms for climbing, a shrub rose will need support and training. This process involves:
Providing the right soil: Rich, well-drained soil is crucial for encouraging tall growth. Pruning: Regular pruning can encourage the plant to produce new, longer canes. Support: Providing a trellis or a sturdy support structure is essential. Training: Securing the canes to the support structure using tying methods. Winter protection: In cold climates, protection of the taller canes is necessary to avoid frost damage.Examples of Shrubs Rose Climb Training
For a more natural climbing effect, you could train a shrub rose like 'Blush Delight' or 'Joseph's Coat' using the fans and interlacing technique. This involves creating a series of layered canes that can be trained against a lattice or an arch. The key is to start early in the plant's life and to be patient. Each year, you can train and tie the new canes to achieve the desired shape.
The Case for Climbing Roses
For those who strictly need a climbing rose, there are several varieties that are specifically bred for this purpose. Climbing roses, such as 'Blaze', 'Cupid', and 'Iceberg', are genetically modified to produce the necessary growth habits and structures to climb a trellis or wall. These roses can grow up to 20 feet tall and are known for their strong canes and ease of training.
Conclusion
While shrub roses are not bred to climb without significant training, it is possible to achieve a climbing effect with the right care and techniques. Climbing roses are a different breed, designed with the specific purpose of climbing in mind. Understanding the difference between these types of roses will help you choose the right plant for your garden based on your specific needs and aesthetic preferences.
