Centuries of gardeners have chosen peonies as a garden staple. In fact, peonies were the main flower in the Chinese Imperial Palace Gardens, and under imperial protection, as far back as 600 A.D. Largo peonies are one of many different peony cultivars available to gardeners today. Largo peony plants feature stunning pink blossoms that add vibrant color to your garden or to freshly cut floral arrangement.
Largo peonies, bloom from late spring through the middle of summer. Plants are hardy in U.S. Department of Agriculture planting zones 4 through 8 and grow to heights and widths of 2 to 3 feet. Largo peonies are a Japanese variety featuring showy large, rounded flowers with rosy-pink petals that surround a rounded central ball with a similar color. Staminodes are pink with yellow tips. Leaves are medium-sized and green. Plants produce a single flower on each stem and are deer resistant.
Largo peonies prefer full sunlight and well-draining soil with a pH of approximately 6.5. When selecting the location for planting your Largo peonies, be sure to select a permanent spot — peonies cannot be transplanted for three years after initial planting. The area that you choose should be free from any competing root systems, preferably a spot that also provides shelter from any potential heavy winds. Prepare the soil by plowing or tilling to area to depths of 1 to 3 feet. Incorporate organic materials, such as compost, into the soil to enrich its nutrient content. Allow the soil to settle for three to seven days prior to planting.
According to Kansas State University, the best time to plant peonies is during early autumn, before the ground completely freezes. Since peony plants become dormant in August, planting in autumn provides optimal timeframe for the soil to settle around the plant’s roots, diminishing the chance that the newly planted roots will be damaged by winter temperatures. Fall-planted peonies will have a more vigorous bloom during the first year than peonies planted in spring, since the roots have more time to become established.
Dig a hole that will accommodate the Largo peony plant’s roots without overcrowding them. Buds should be 1 inch below the soil’s surface if you have clay soil and 3 inches below the surface if you have light, sandy soil. Plant peonies in rows with between 2 and 3 feet between plants and 4 feet between rows. Fill soil in around each plant’s roots, gently firming the soil to prevent any air pockets from potentially damaging the root system. Water each plant with 1 gallon of water, allow the water to settle and add more soil to the plant, creating a mound around each plant to provide winter protection.
