Paeonia lactiflora ‘Karl Rosenfeld’, commonly known as Karl Rosenfeld Peony, is a classic perennial celebrated for its large, deep crimson-red, double blooms and delightful fragrance. Blooming in late spring to early summer, this peony grows 2 to 3 feet tall and wide, making it a standout in borders, cottage gardens, and formal landscapes.

With its showy flowers and sturdy stems, Karl Rosenfeld Peony is an excellent choice for cut flower arrangements. While this garden favorite provides stunning visual appeal and some pollinator attraction, it is not a native species, and native plants offer greater ecological benefits to local pollinators and wildlife.
