Botanical Name

Paeonia lactiflora 'Karl Rosenfield'

Commonly known as Karl Rosenfield Peony

Paeonia lactiflora 'Karl Rosenfield' (Karl Rosenfield Peony)
Perennial

Deep ruby-red double blooms with ruffled petals on strong stems. One of the most reliable red peonies and a heritage cultivar still unmatched.

Toxic to cats

The ASPCA lists peony (Paeonia officinalis) as toxic to cats and dogs, and to horses. Eating it can cause vomiting, diarrhoea and listlessness. The ASPCA names that one species, but ours are the same genus, so give them the same caution, and keep a vase of cut stems out of a cat's reach.
