Paeonia lactiflora 'Karl Rosenfield'

paeony or peony

Product Image
Prized for their blowsy, glamorous blooms and glossy, deeply cut foliage, peonies are held in deep affection by many gardeners. From the promise of early spring, when 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.

Perfect for borders or as a focal point, Paeonia lactiflora 'Karl Rosenfield' combines beauty with reliability, and long vase life, making it a favourite for classic and contemporary garden designs alike.

How to care for Paeonia lactiflora Karl Rosenfield:

Where available, bare root peonies should be planted out or potted up as soon as possible, avoiding frosty or waterlogged conditions. Choose a sunny, well-drained position, as peonies flower best in full sun and dislike being moved once established.

Plant all peonies into well-prepared soil, ensuring the highest bud on the crown is no deeper than 5cm (2in) below the surface. For newly planted plants, protect emerging shoots from late frosts in their first spring. Keep plants well watered and fed during growth, using balanced, slow-release fertiliser rather than high-nitrogen feeds, and remove spent flowers once faded.

Mulch with well-rotted compost or manure, support tall stems to prevent flopping, maintain good air circulation, and remove any yellowing or diseased leaves. Avoid disturbing established crowns, as peonies dislike being moved may take a season or two to establish.
