Prized for their big, glamorous blooms and glossy, deeply cut foliage, peonies are held in deep affection by many gardeners, despite their shortish flowering season and vulnerability to peony wilt in damp weather. It's easy to see why. From the promise of early spring, when their red, mottled shoots push through bare earth and the handsome foliage unfurls from spherical red buds, to early summer, when the huge flowers burst open, peonies exert a fascination that few can resist. 'Karl Rosenfield' has fragrant double flowers of startling magenta, from early to mid-summer among deeply cut mid-green leaves. The reddish-bronze foliage of this striking peony provides interest from early spring and after the plant has flowered.
How to care for Paeonia lactiflora Karl Rosenfield:
Bare root plants should either be potted up or planted out as soon as possible while avoiding frosty or waterlogged conditions. Plant all peonies into well-prepared soil, making sure that the highest bud on the crown is no deeper than 5cm (2in) below the soil surface. In growth, keep well fed and watered, and remove spent flowers after they have faded. In each subsequent spring, apply a balanced slow-release fertiliser around the base of the plant and mulch with well-rotted compost or manure.
