According to George, Knock Out is extremely easy to grow, even for those brand new to gardening, and is so pest tolerant that almost never will pesticides need to be applied.

The Texas Superstar effort is one of the Texas A&M system's most innovative and successful horticultural research and Extension programs, said George.
"Only the best adapted, highest performing and most pest-resistant plant materials are designated Texas Superstars, and should include the Texas Superstar pot label," he said.
Knock Out was also named an EarthKind rose by Texas A&M horticulturists this year. Only a few roses receive the EarthKind designation. Winners not only have to deliver outstanding landscape performance under widely varying soil conditions with minimal care and impact to the environment, but they have to be beautiful as well.
"A key component of both the EarthKind and Texas Superstar designations is that a rose's tolerance to pests is so great that you "will almost never have to apply harsh pesticides in the care of these roses," George said. "EarthKind and
