Rosa

Rose - Knockout

The Knockout Rose Series is a series of very hardy shrub roses that have proven themselves in the landscape time after time.  Heat tolerant and durable, the Knockouts are the most disease resistant roses on the market today.  We recommend using them as you would any shrub in a sunny landscape, rather than treating them as a rose.  This group of roses rebloom all season long. Great for small spaces, hedges or mixed borders.
