Everyone loves roses, but unless you’re a gardening pro, they can be difficult to maintain. In 2000, Milwaukee rose breeder William Radler changed the history of rose gardening when he introduced what would become the world’s bestselling rose, the Knock Out® rose. Home gardeners love Knock Out roses because they are extremely easy to care for compared to traditional roses, and bloom continuously through spring and summer all the way up to the first frost.
Knock Out roses can be planted in direct sunlight, and do not require any special care or separation from the rest of your garden. You don’t even have to remove spent blooms. Knock Out roses come in 10 different colors, allowing you to create fantastic mix-and-match displays.
