What is the difference between knockout and double knockout roses? At their core, both types of roses are known for their hardiness and low maintenance, making them popular choices for gardeners. However, the primary difference lies in their bloom structure: knockout roses typically have a single layer of petals, while double knockout roses feature a fuller, more lush appearance with multiple layers of petals.
Understanding Knockout Roses
Knockout roses have revolutionized the gardening world since their introduction. Known for their resilience, these roses are highly disease-resistant and can thrive in a variety of climates.
