#ProPlantTips For Care
Growing Peonies is a breeze! Performing best in full sun is best to really make the blooms and foliage shine! Karl Rosenfield especially is adaptable to a wide variety of soil types however, Peony root systems will always need well-drained soil.
Extremely cold tolerant, northern gardeners to cold hardiness zones of 4 and up will be delighted to know how tough this plant is! However, even warmer growing zones up to 8 will get to enjoy these luxurious blooms!
Karl Rosenfield does best without sun and nutrient competition, so avoid planting too close to larger shrubs and trees.
Forming a neat and lush clump that won't stray from where it is planted, there will be no need to divide these plants. Like all Peony, it will benefit from support if your area tends to have strong amounts of summer rainfall.
This long-lived herbaceous perennial is quite easy to care for. As the blooms fade, cut off the old flowers leaving the foliage in place to make food for next year. Then in fall after the frost kills off the foliage, cut all of the stems down to the ground and remove all of the debris to prevent overwintering fungus spores for next year to help keep your plants clean and healthy.

Very hardy and extremely long-lived, Peony shrubs have stood the test of time. These tough plants have been known to live for 50 years!
Our love for them hasn't waivered much either, considering these wonderful plants have been around for centuries!
