The full double paeonia ‘Karl Rosenfield’ is a rewarding summer bloomer that flowers in the months of May-June. Paeonia ‘Karl Rosenfield’ grows to a height of about 90-100 cm so it may be necessary to support the flower stems. Paeonia tubers can be planted in the spring. Dig a spacious planting hole, loosen the soil and fill the planting hole with good potting soil. Carefully place the tubers in the planting hole and cover with 3-5 cm soil. The planting distance of the tubers is 30-60 cm. Water the tubers immediately after planting. Paeonia bloom most profusely in full sun. The dark pink-red flowers are real eye-catchers in the border. Paeonia ‘Karl Rosenfield’ is an excellent cut flower and has a long vase life. The best time to cut paeonia is early in the day. Immediately place the stems in lukewarm water with cut flower food.
