The Prickly Truth: Understanding Rose Thorns (or Prickles!)
Let’s get right to it. The straightforward answer is: Yes, the vast majority of climbing roses have thorns. They are a defining characteristic of the plant. However, the story is a bit more interesting than a simple “yes.”
A Quick Botany Lesson: Thorns vs. Prickles
As a gardener, here’s a fun fact you can share with your friends: roses don’t technically have thorns. Botanically speaking, they have prickles.
- Thorns are modified stems or branches, deeply embedded in the plant’s vascular system. Think of the sharp points on a Hawthorn tree. Removing one causes significant damage.
- Prickles, on the other hand, are outgrowths of the stem’s outer layer, the epidermis. They are more like very tough hairs. This is why you can sometimes snap a “thorn” off a rose stem cleanly.
While we all call them thorns, knowing they are prickles is useful. It tells us they aren’t as integral to the stem’s life, and it explains why the density and size of prickles can vary so dramatically from one rose variety to another.
Why Do Roses Have Them Anyway?
These sharp points aren’t just there to annoy gardeners! They serve two crucial evolutionary purposes for the rose.
- Defense: The most obvious reason is protection. Prickles make the rose canes unappetizing to grazing animals like deer and rabbits, who would otherwise happily munch on the tender new growth.
- Support: For climbing roses, prickles act like natural grappling hooks. In the wild, they use them to latch onto other plants and scramble their way up towards the sunlight. This is a key part of how they “climb.”
The Unexpected Benefits of Thorny Roses
Before you rush to find a completely smooth-stemmed variety, it’s worth considering the upsides of a thorny climber. This is one of the more surprising benefits of does climbing rose have thorns discussions we have at Greeny Gardener!
A well-placed thorny rose can be a beautiful and effective natural deterrent. Planting a vigorous, thorny climber like ‘John Cabot’ or ‘New Dawn’ along a fence line can discourage unwanted two-legged and four-legged visitors from taking shortcuts through your yard.
Furthermore, that dense, prickly structure provides an incredibly safe haven for small birds. They can build nests deep inside the canes, protected from predators like cats or hawks. Watching a family of finches raise their young in your rose bush is a truly special gardening reward.
The Holy Grail: Finding Nearly Thornless & Smooth-Stemmed Climbers
Okay, you appreciate the purpose of thorns, but you’re still dreaming of a less “bitey” rose for your high-traffic patio or entryway. Don’t worry—you have fantastic options! Many breeders have cultivated stunning climbers with very few prickles.
Here is our list of tried-and-true, nearly thornless climbing roses. They make the entire process of training and pruning a breeze. Don’t worry—these flowers are perfect for beginners!

Your Complete Does Climbing Rose Have Thorns Care Guide
Whether you choose a thorny beast or a smooth-stemmed beauty, the fundamentals of care are the same. Following this does climbing rose have thorns care guide will ensure your climber thrives and smothers its support in glorious blooms.
Choosing the Right Spot
Success starts with location. Climbing roses are sun-lovers and need at least six hours of direct sunlight per day to produce abundant flowers and stay healthy. Good air circulation is also key to preventing fungal diseases like black spot.
Ensure you have a sturdy support structure in place before you plant. This can be a trellis, an arbor, a pergola, or a system of strong wires installed on a wall. Give your rose room to grow!
Planting Your Climber Correctly
Dig a hole that is twice as wide and just as deep as the pot your rose came in. Mix some good quality compost or well-rotted manure into the soil you removed. This gives your new plant a nutrient-rich start.
Gently tease out the roots at the bottom of the root ball and place the plant in the hole. For grafted roses, ensure the bud union (the swollen knob at the base of the plant) is at or slightly above soil level. Backfill the hole, firm the soil gently, and water deeply.
Training for Maximum Blooms
This is the secret to a spectacular display! Do not train the main canes to grow straight up. Instead, aim to bend and tie the flexible canes as close to horizontal as possible.
This technique tricks the plant into sending up short, vertical flowering shoots (called laterals) all along the length of the horizontal cane. The result? Far more flowers from top to bottom, rather than just a few blooms at the very top.
How to Handle Thorny Roses Safely: Best Practices & Tips
If you’ve fallen for a rose with formidable armor, fear not. With the right gear and techniques, you can manage it without a scratch. This is our essential list of does climbing rose have thorns tips.
The Essential Gear
Investing in good protective gear is non-negotiable. It transforms pruning from a painful chore into a pleasant garden task.
- Gauntlet Gloves: These are a game-changer. Look for thick leather gloves that extend up your forearm to protect your arms from swinging canes.
- Long Sleeves: A sturdy long-sleeved shirt or a dedicated pair of gardening sleeves will prevent countless scratches.
- Eye Protection: A simple pair of safety glasses is a must. A stray branch whipping back can cause serious eye injury.
Pruning with Confidence
The best time to prune most repeat-flowering climbers is in late winter or early spring, just as the buds begin to swell. The goal is to remove dead, damaged, or diseased wood and to shape the plant.
Always use clean, sharp bypass pruners. When removing a large, thorny cane, cut it into smaller, more manageable pieces before trying to pull it out of the plant. This prevents it from getting tangled and snagging everything (including you) on its way out.
Disposing of Thorny Cuttings
Don’t just toss thorny branches into your general yard waste bin where they can poke an unsuspecting family member or sanitation worker. A great eco-friendly does climbing rose have thorns practice is to chop them into smaller pieces with long-handled loppers and place them in a sturdy paper yard waste bag or a dedicated compost pile for woody materials.
Sustainable and Eco-Friendly Rose Care
A healthy rose is a beautiful rose. Embracing sustainable practices will not only benefit your plant but the entire garden ecosystem.
For a truly sustainable does climbing rose have thorns approach, start with the soil. Top-dressing with compost annually provides a slow-release source of nutrients. Use organic mulches like shredded bark or leaf mold to retain moisture, suppress weeds, and enrich the soil as it breaks down.
Avoid chemical pesticides whenever possible. Often, a strong jet of water from the hose is enough to dislodge aphids. Encourage beneficial insects like ladybugs and lacewings, which are voracious predators of common rose pests. A healthy, well-fed, and properly watered plant is its own best defense against disease.
Common Problems with Climbing Roses (and How to Solve Them)
Even with the best care, you might encounter a few issues. Here’s a quick guide to some common problems with climbing rose have thorns situations.
- Black Spot: Dark, circular spots on leaves that later turn yellow.
Solution: Improve air circulation. Water at the base of the plant, not on the leaves. Remove and dispose of affected leaves (do not compost them). - Powdery Mildew: A white, dusty coating on leaves and buds.
Solution: Usually caused by poor air circulation and humid conditions. Prune to open up the plant. A spray of horticultural oil can help. - Aphids: Tiny insects clustered on new growth and buds.
Solution: A strong spray of water, encouraging beneficial insects, or a gentle application of insecticidal soap. - Not Blooming:
Solution: Check for at least 6 hours of sun. Ensure you are not over-fertilizing with nitrogen (which promotes leaf growth at the expense of flowers). Re-evaluate your pruning—you may have cut off the wood that was meant to bloom.
Frequently Asked Questions About Climbing Rose Thorns
Can I remove the thorns from my climbing rose?
You can, but it’s not generally recommended. Scraping or cutting the prickles off can create small wounds on the cane, providing an entry point for diseases. It’s also incredibly time-consuming. It’s far better to choose a naturally low-thorn variety if prickles are a major concern.
Are any climbing roses completely 100% thornless?
Truly 100% thornless roses are exceptionally rare. Even the famously smooth ‘Zephirine Drouhin’ can occasionally produce a small prickle or two, especially on older, woodier growth. It’s more accurate to think of them as “virtually” or “nearly” thornless.
What are the most thorny climbing roses I should be aware of?
Some varieties are legendary for their armor! Many old ramblers, like ‘Kiftsgate’ and ‘Albertine’, are notoriously vigorous and ferociously thorny. While stunningly beautiful when mature, they require a lot of space and a very brave, well-gloved gardener.
Your Vertical Garden Awaits!
So, does climbing rose have thorns? Yes, most do. But as you’ve seen, that’s just the beginning of the story. Thorns are a part of the rose’s character, but they don’t have to be a barrier to your gardening dreams.
By understanding their purpose, choosing the right variety for your needs—whether it’s a smooth-stemmed beauty or a thorny protector—and using the right safety gear, you can confidently manage and enjoy any climbing rose.
