SALT LAKE CITY — Shrub roses can be easy to grow just about anywhere in the nation due to the flower’s hardiness in a variety of climates around the United States.
The KSL Greenhouse Show hosts Maria Shilaos and Taun Beddes shared facts on Saturday about the rose, known to many as the knock out rose, and how to take care of it in Utah.
KSL NewsRadio edited the following transcript for brevity.
Beautiful, yet hardy
BEDDES: “Knock out roses are shrub roses. They grow in a mound three to four feet wide with some pruning, and they will freely bloom throughout the summer, especially if you will give them a light haircut when a flush of blooms are done, they just keep pushing new flushes of blooms all summer. In addition to that, they are disease and pest resistant.
SHILAOS: “Kind of a new variety? Can I call it that?”
BEDDES: “The last 20 years, yes, there’s been. The original knock out rose is red and it was an all American selection, it was like the rose of the year, because of how well it performed across the country. It was cold hardy, yet it grew in Florida, in Texas, where those climates can be really tough on roses. It’s one that’s a useful, beautiful shrub that you can use in your yard. It’s even somewhat water wise.
Doesn’t look like a typical rose
SHILAOS: “But the flower doesn’t look exactly like what you’d think a rose looks like?”
BEDDES: “No. It has a simple flower and so it looks a little more like, almost like an heirloom rose. But it’s a repeat bloomer.”
