Meet the next generation of Knock Out®.

Triple Knock Out® is unlike any rose previously introduced into the Knock Out® family.

For the first time, the famously easy-growing Knock Out® genetics have been combined with a fuller, more traditional garden-rose flower and noticeable fragrance.

The result is so different that Triple Knock Out® also becomes the first Grandiflora ever introduced into the Knock Out® family.

Its rich red to deep-pink flowers contain approximately 30–35 petals—roughly three times the petals of the original Knock Out®.

And yes.

This Knock Out® has fragrance.

A noticeable sweet floral perfume adds an entirely new dimension to a rose already bred for exceptional garden performance.

3️⃣ Why Is It Called Triple Knock Out®?

Here's where the name gets fun.

The original Knock Out® carries approximately 7–11 petals per flower.

Triple Knock Out® averages around 35 petals.

That's roughly three times the petals of the original.

Those extra petals completely change the appearance of the flower.

Instead of the simpler, open landscape-rose bloom traditionally associated with Knock Out®, Triple Knock Out® produces a much fuller flower with the romantic appearance of a traditional garden rose.

It's still unmistakably Knock Out®.

It just got dressed up.

🌹 A First for the Knock Out® Family

Triple Knock Out® represents an important new chapter in the history of the brand.

For more than two decades, the Knock Out® family has been synonymous with landscape shrub roses—roses selected for prolific flowering, disease resistance, and uncomplicated garden performance.

Triple Knock Out® changes the formula.

It is the family's first Grandiflora.

It has triple the petals of the original.

And it offers a more noticeable fragrance than its predecessors.

Before earning the Knock Out® name, Triple Knock Out® underwent extensive trialing to ensure it could still deliver the disease resistance, hardiness, vigorous growth, and reblooming expected from the family.

So this isn't simply a prettier Knock Out®.

It's a new kind of Knock Out®.

👃 Finally, a Knock Out® for Fragrance Lovers

This may be one of the most exciting differences.

Triple Knock Out® has a noticeable sweet floral fragrance.

That means gardeners who loved the performance of Knock Out® roses but wanted a fuller, more fragrant flower finally have an option designed to deliver both.

Fuller flowers.

More perfume.

Same easy-going attitude.

💛 Why Grace Rose Farm Loves It

This is Knock Out® all grown up.

The original Knock Out® changed the rose industry by proving that roses didn't have to be difficult to be spectacular garden plants.

Triple Knock Out® takes that idea somewhere new.

You still get the qualities that made the family famous: repeat flowering, exceptional disease resistance, a compact habit, and easy garden performance.

But now you get something many rose lovers have been asking for:

A fuller flower and noticeable fragrance.

And with approximately 30–35 petals, those deep red-to-pink blooms look much more like the traditional roses many of us fell in love with in the first place.

For beginning rose gardeners, landscape gardeners, and experienced collectors who secretly want a few roses they don't have to fuss over, this one is going to be fun.

Triple the petals. Triple the romance.

🌿 Growing & Care Recommendations

Planting Site: Choose a sunny location receiving at least 6 hours of direct sunlight each day.

Spacing: Allow approximately 2–3 feet between plants to accommodate its mature width and maintain good air circulation.

Watering: After planting your bare-root rose, water deeply and consistently while new roots and shoots establish.

Pruning: Knock Out® roses can be cut back in early spring after the threat of hard frost has passed. Remove dead or damaged wood and shape the plant as needed.

Maintenance: Triple Knock Out® was bred for uncomplicated garden performance and does not require routine spraying or deadheading to continue producing healthy growth and flowers.

Mass Planting: At approximately 3 feet tall, Triple Knock Out® is an excellent candidate for planting in groups to create a long-flowering sweep of rich red and deep pink.

Cold-Climate Bonus: With hardiness listed to USDA Zone 4b, Triple Knock Out® brings this fuller flower form to gardeners well beyond traditional warm-climate rose regions.
