Karl Rosenfeld Peony
Paeonia lactiflora ‘Karl Rosenfeld’Karl Rosenfeld Peony is a classic herbaceous perennial valued for its large, richly colored blooms and dependable late spring display. In late spring to early summer, it produces abundant double flowers in deep, vibrant fuchsia tones. The blooms are full and ruffled with layers of petals, creating a bold, luxurious appearance that stands out strongly against the foliage and adds rich color to perennial borders and garden beds.
The flowers are carried on sturdy, upright stems above lush, deeply divided green foliage. The foliage remains attractive throughout the growing season, forming a dense, bushy mound that provides structure and texture even after flowering has finished. Once established, this peony forms long-lived clumps that improve in performance and bloom density year after year.
Karl Rosenfeld typically grows 2.5 to 3 feet tall with a similar spread, forming a rounded, well-behaved clump. Its strong stems generally support the heavy blooms well, though staking may be helpful in windy or exposed locations. The bold flower color makes it especially effective in mixed perennial borders, cottage gardens, and as a specimen planting.

Fertilizing: Apply a balanced fertilizer in early spring.
Pruning: Cut foliage back in fall after it dies back naturally.
Spacing: Space plants 2.5–3 ft apart for airflow and mature growth.
Maintenance: Staking may be needed for large blooms.
This peony thrives in full sun and prefers rich, well-drained soil. It benefits from a cold winter period to ensure strong flowering in spring. Once established, it is very low-maintenance and long-lived, often thriving in the same location for decades with minimal care.
