The introduction of the Knock Out Rose family has completely changed the world of rose gardening. Never before have so many gardeners been able to grow fabulous roses even in cold climates and with very little time commitment. This collection of roses is definately a knockout in a lot of ways, but the easy care combined with fantastic blooming qualities puts them at the top of the zone 5 gardeners list! The blooming is amazingly floriferous in striking color all season long. Knock Out roses are completely hardy in zone 5, many gardeners claiming the same in zone 4. It is definately a good idea to mulch heavily in zone 4, and consider more extensive winter protection methods in colder zones, especially if snow cover is not reliable. (Zone 2 and 3 gardeners might want to consider the Canadian bred Explorer or Parkland Roses or Rugosa Roses for easy care in even colder climates.) The excellent resistance to disease also makes the Knock Out family a great choice for humid climates where rose disease and fungus can be a problem. Use Knock Outs anywhere in your gardens and landscape. Their smaller size and dense growing habit makes them perfect for accent and specimen plants, bordering gardens, sidewalks or driveways, mass plantings, and they are great in container. |

Sunny Knock Out is the only fragrant rose of the family. The fragrance does not come from the blooms, but is released by the petioles. It also grows a bit more upright and dense than the others.

Will do well in zones 3 and 4 with winter protection. Home Run
‘Home Run’ is a Knock Out hybrid by Tom Carruth of Weeks Roses, that offers even better resistance to fungus than the original Knock Out family.

Blooms are produced in clusters and are a deeper red in cool weather. The shrub has a very nice rounded form. Foliage turns a rich burgundy in fall.
