I tried to think of a witty introduction to this post but it didn’t work. Yes, I know I wrote about rose hips on Monday and I have two more rose-related posts in the works, but I find roses kind of intimidating. We had roses growing up so it’s not like I haven’t been around them before, I’ve just never been the one responsible for their care. There’s part of me that thinks I’ll mess up somehow and I really don’t want to kill the roses I just put in.
Anyways, the subjects of today’s short post are two terms I came across while rose shopping that I had never encountered of before. Since I ended up purchasing self-cleaning Knock Out® roses I figured I should learn just what those terms mean and what to expect from my plants.
What are Knock Out® roses?
Knock Out® roses are a variety of shrub roses that were bred by William J. Radler in 1989. They were introduced to the public in 2000 by Star Roses. Knock Out® roses are very hardy and resistant, though not immune, to diseases. They grow vigorously and have 4 or more bloom cycles (will bloom 4 or more times a year). The original Knock Out® rose was red, but the color options have expanded to include yellow, pink, and pale pink.
What are self-cleaning roses?
Self-cleaning roses are roses that drop their spent blooms instead of requiring deadheading. They will bloom multiple times on their own but won’t produce rose hips.
