The 'Karl Rosenfield' peonia lactiflora produces large, full flowers of a unique crimson colour. External petals are large, wide and waved. Internal petals are narrow, tucked, and crenate. In the full flowering period yellow stamens become visible. The 'Karl Rosenfield' peonia lactiflora is fragrance-free. Long shoots are not thick though and due to this supports may be necessary. It is also cultivated for cut flowers.
