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 first of its kind to allow just about anyone to grow a rose. Although the rose shrub lacks scent like heirlooms or tea roses it is disease resistant. The knock out rose shrub can grow as tall as 4 feet in most any landscape. It is the first of its kind to be immune to the fungal diseases of other roses. This means the rose can grow organically with only issues from aphids. Aphids can be treated organically but I have never had a problem with these bugs. If it weren’t for the knock-out rose many would never have been able to grow roses in their home garden.
Below are my first 2 knock out roses growing in zone 5b Ohio.
History of the Knock-Out Rose Shrub
The Knock Out® rose was developed by William Radler in the 1970s. The first true Knock Out® rose started as only one seed in 1989. It wasn’t until 2000 when the red knock our rose received the “All America Rose Selection” from The American Rose Society. Below are a few of my favorites I have grown in my Ohio garden. It is impossible to pick my favorite out of all the varieties.
- 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.
Happy Birthday, Knock-Out Rose,
