Paeonia lactiflora 'Sarah Bernhardt'
Fully double, apple-blossom pink blooms so heavy they nod on their stems. The most planted peony in history.
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.
For gardeners who like to stay ahead.
