Grafted or Own-Root: What Are Bare Root Roses?
When you unwrap a bare root rose for the first time, the knobby bump near the base of the plant usually raises questions. That swollen joint tells a story about how the rose was produced, and understanding it changes the way you plant, prune, and care for the bush for years to come. Whether your bare root rose arrived grafted or growing on its own roots affects everything from cold hardiness to the suckers you will need to manage each season.
How Commercial Rose Production Works
The vast majority of bare root roses sold through nurseries, garden centers, and mail-order catalogs arrive as grafted plants. Commercial rose growers use grafting because it allows them to mass-produce popular varieties faster and more reliably than growing each one from cuttings or seed.
The process starts with a vigorous rootstock variety, usually Rosa multiflora or Dr. Huey, grown specifically for its strong root system. Once the rootstock reaches the right size, a grower takes a bud from the desired rose variety and attaches it to the rootstock stem through a technique called bud grafting. The bud heals into the rootstock, and the new combined plant eventually becomes the bare root rose you purchase.
This method gives commercial growers a major advantage. They can produce thousands of identical roses in a single growing season, each one benefiting from a rootstock bred specifically for root vigor, disease tolerance, and adaptability to different soil types.
What That Bump at the Base Actually Means
If you look closely at a bare root rose, you will almost always notice a swollen knob where the stem meets the roots. This bump, called the bud union or graft union, marks the exact point where the desired rose variety was attached to the rootstock. Everything above the union produces the flowers you chose. Everything below belongs to a completely different rose variety.
The size and shape of the bud union varies depending on the rootstock used, the grafting technique, and how long the plant has been growing. Some unions are barely noticeable, while others form a fist-sized bulge that looks almost like a tumor. Both extremes are perfectly normal and do not indicate any health problems with the plant.
Knowing where the graft union sits matters when you plant. In cold climates, most rose experts recommend burying the union two to three inches below the soil surface to protect it from freezing temperatures. In mild climates, planting with the union just above soil level allows better air circulation and makes it easier to spot rootstock suckers.
Why Nurseries Prefer Grafting Over Own-Root Methods
Speed and economics drive the preference for grafted roses in the commercial industry. A grafted rose can reach saleable size in roughly one growing season, while an own-root rose grown from a cutting often takes two to three years to develop enough roots and top growth to survive transplanting.
Grafted roses also tend to establish faster after planting. The mature rootstock already has a well-developed root system capable of pulling water and nutrients from the soil immediately. Own-root roses need time to build that root infrastructure from scratch, which means slower growth and fewer flowers during the first year or two.
| Factor | Grafted Bare Root Roses | Own-Root Bare Root Roses |
|---|---|---|
| Production time | One season | Two to three seasons |
| First-year vigor | Strong, fast establishment | Slower initial growth |
| Long-term hardiness | Depends on rootstock | Matches the variety itself |
| Sucker risk | Yes, from rootstock | No rootstock suckers |
| Cold damage recovery | May revert to rootstock | Regrows true to variety |
| Availability | Very common | Less common, specialty growers |
| Typical cost | Moderate | Often slightly higher |
These production advantages explain why the overwhelming majority of bare root roses on the market come grafted. When you order from a mainstream catalog or pick up a dormant rose at your local garden center during late winter, you are almost certainly getting a grafted plant.
Identifying Whether Your Bare Root Rose Was Grafted
Telling a grafted rose apart from an own-root rose takes just a few seconds of inspection. Look at the area where the canes emerge from the root system. A grafted rose shows a clear transition point, that distinctive swollen bud union, where the wood color or bark texture changes between the upper plant and the rootstock below.
An own-root rose grows seamlessly from roots to canes with no visible junction, bump, or change in bark character. The stem simply tapers smoothly into the root system the same way a naturally grown shrub would.
If you received your bare root rose through mail order, the packaging or label often indicates the rootstock used. Common rootstock names to look for include:
- Dr. Huey — the most widely used rootstock in North America, known for dark red blooms if it sends up suckers
- Rosa multiflora — extremely vigorous, commonly used for commercial production
- Fortuniana — popular in warm climates like Florida and the Gulf Coast
- Rosa laxa — common in European rose production, favored for alkaline soils
If your label does not mention a rootstock and you cannot see a bud union, you likely have an own-root plant. Specialty growers like David Austin and some heritage rose nurseries sell a growing number of roses on their own roots.
The Sucker Problem With Grafted Bare Root Roses
One of the most frustrating issues unique to grafted roses involves rootstock suckers, vigorous shoots that emerge from below the graft union. These suckers grow from the rootstock rather than from the desired rose variety, and they will eventually overtake the plant if left unchecked.
Rootstock suckers typically look different from the rest of the bush. They often have a different leaf shape, a different number of leaflets per stem, lighter green color, and smaller thorns. Dr. Huey suckers, for example, produce clusters of small, dark red semi-double flowers that look nothing like the hybrid tea or floribunda you originally planted.
Removing suckers properly requires tracing them back to their origin point on the rootstock and pulling or cutting them off flush. Simply snipping them at ground level encourages them to regrow even more vigorously. A pair of long-handled bypass pruners makes it easier to reach the base of suckers without disturbing the surrounding soil too much.
Checking for suckers every few weeks during the growing season prevents them from sapping energy away from the grafted variety above.
When Own-Root Bare Root Roses Make More Sense
Despite the commercial dominance of grafted plants, own-root roses have significant advantages in certain situations. Gardeners in extremely cold climates, particularly USDA zones 3 and 4, often prefer own-root varieties because of what happens when winter kills the top growth down to the ground.
When a grafted rose dies back below the bud union, the desired variety is gone permanently. Whatever regrows from the roots will be the rootstock variety, not the rose you paid for. An own-root rose that suffers the same winter damage will regrow true to its variety because the roots and the top growth share the same genetics. This makes own-root roses essentially immortal in terms of variety preservation, as long as the roots survive.
Own-root roses also eliminate the sucker problem entirely. Since there is no foreign rootstock, every shoot that emerges from the base or the roots belongs to the same variety. This reduces maintenance and removes the risk of the rootstock gradually taking over the plant.
For gardeners who want to explore own-root options, many shrub roses, David Austin English roses, and old garden roses are now available on their own roots from specialty nurseries. The initial slower growth is a trade-off most experienced rose growers are happy to accept for the long-term benefits.
How to Plant a Grafted Bare Root Rose Correctly
Planting depth matters more for grafted bare root roses than almost any other garden plant. Getting the bud union at the wrong depth can lead to winter damage, excessive suckering, or poor establishment.
Follow these steps for the best results:
- Soak the entire bare root plant in a bucket of water for eight to twelve hours before planting
- Dig a hole wide enough to spread the roots without bending them, roughly 18 inches across
- Build a small cone of soil in the center of the hole to support the root system
- Position the plant so the bud union sits two to three inches below soil level in cold climates or just at soil level in warm regions
- Spread the roots evenly over the soil cone
- Backfill with a mixture of native soil and compost, firming gently as you go
- Water deeply to settle the soil and eliminate air pockets
- Apply a three-inch layer of mulch around the base, keeping it a few inches away from the canes
A bag of organic rose planting compost mixed into the backfill gives roots a nutrient-rich environment to grow into during the first critical weeks after planting.
Caring for Grafted Roses Through the First Season
The first growing season after planting a bare root rose sets the foundation for years of blooms. Grafted bare root roses need consistent moisture during the first three months as the rootstock establishes new feeder roots in the surrounding soil.
Water deeply twice a week rather than lightly every day. Deep watering encourages roots to grow downward into cooler, more stable soil layers. Shallow watering keeps roots near the surface where they are vulnerable to heat stress and drought.
Resist the urge to fertilize heavily right away. A light application of a slow-release rose fertilizer about four weeks after planting gives the plant a gentle nutritional boost without overwhelming the developing root system. Heavy feeding too early can burn tender new roots and set the plant back rather than pushing it forward.
Remove any flower buds that form during the first six weeks after planting. This feels painful, but it redirects the plant's energy away from blooming and into root and cane development. A bare root rose that builds a strong framework during its first season will reward you with significantly more flowers in every season that follows.
Grafted Versus Own-Root for Specific Rose Types
The question of grafted or own-root becomes especially relevant depending on which type of rose you want to grow. Different rose categories respond differently to each production method.
Hybrid tea roses almost always perform better as grafted plants. Their naturally weak root systems benefit enormously from the vigor of a strong rootstock. Without grafting, many hybrid teas struggle to produce enough energy to support their large, high-centered blooms.
Climbing roses handle both methods well, though grafted climbers tend to establish faster on walls and trellises. Own-root climbers may take an extra season to begin their upward growth in earnest.
Shrub and landscape roses like the Knock Out series and Drift roses often perform equally well on their own roots or grafted. Many modern landscape roses are increasingly sold as own-root plants because they are bred for vigor and disease resistance that does not depend on a separate rootstock.
Old garden roses and species roses frequently thrive on their own roots and may actually perform worse when grafted onto an incompatible modern rootstock. If you are growing Damask, Gallica, or Bourbon roses, seeking out own-root specimens from a specialty grower often gives the best long-term results.
Protecting the Graft Union in Winter
For gardeners in zones 5 and colder, protecting the bud union through winter prevents the most common cause of grafted rose death. Even varieties rated as cold-hardy can lose their graft union during a severe cold snap if it is exposed above the soil surface.
The traditional method involves mounding eight to ten inches of soil or compost over the base of the plant after the first hard frost in fall. This insulating layer keeps the bud union at a more stable temperature throughout winter, even when air temperatures plunge well below zero.
A rose bush winter protection cone placed over the mounded soil adds an extra layer of wind and cold protection in the harshest climates. Remove the cone and gently pull the soil mound away in early spring once forsythia begins blooming in your area, which signals that the worst cold has passed and the rose can safely begin its new season of growth.
