It feels just like yesterday I brought my first Knock-Out Rose Shrub home. Happy Birthday knock out hits 10 today! In this post, I share a few images and facts about the beloved Knock-Out Rose.
Happy Birthday Knock-Out Rose

The Knock Out rose shrub was the pioneer in making rose cultivation accessible to nearly everyone. While this rose shrub lacks the fragrance of heirloom or tea roses, it boasts impressive disease resistance. Typically reaching heights of up to 4 feet, it fits well into various landscapes. It is the first variety to be resistant to the fungal diseases that affect other roses, allowing it to thrive organically, with only potential issues from aphids. While aphids can be treated with organic methods, I personally have not encountered problems with them. Without the Knock Out rose, many people would not have had the opportunity to grow roses in their home gardens. More Knock-Out Roses on my Website HERE.

History of the Knock-Out Rose Shrub

The Knock Out® rose was created by William Radler in the 1970s. The very first true Knock Out Rose Shrub originated from a single seed in 1989. It wasn’t until 2000 that the red Knock Out rose earned the prestigious “All America Rose Selection” award from The American Rose Society. Here are a few of my favorites that I have cultivated in my Ohio garden. Choosing a favorite among all the varieties is truly a challenge.
- Carefree Sunshine (a yellow rose) introduced in 2001,
- Blushing Knock Out (pale pink) in 2004,
- Rainbow Knock Out (pink with a yellow center) in 2007.
