'Knock Out® (‘Radrazz’)' Rosa (Shrub Rose)

Cultivar Notes -

Knock Out® (‘Radrazz’)

There is hardly anything which will stop this rose from blooming. You can expect to have blooms everyday throughout the summer. We believe that this is one of the best "flowering shrubs" by far to hit the market in quite sometime.

Series Notes -

Knock Out®

Rose breeder, Will Radler has revolutionized the way we think of roses. With the creation of the original Knock Out® Rose, many say that he single-handedly brought rose genetics from the 20th Century into the 21st Century.

The Knock Out® Rose, Radler’s first commercial success and a 2000 AARS winner, has broken all records for sales of a new rose. Today it is the most widely sold rose in North America. Star® Roses and Plants is proud to have introduced all seven members of The Knock Out® Family of Roses.

The Knock Out® Family of Roses are easy to grow and don’t require special care. Plant them individually among shrubs, annuals and perennials in mixed beds and borders. Plant them in large groups to create a colorful hedge or along a foundation to provide a bright border. For best performance, we reccomend cutting them back every year in early spring after the last threat of frost has passed.
