Are anemone de caen perennial

Anemone de Caen, commonly known as Caen anemones, are typically treated as annuals in many gardens, though they are technically perennial in their native habitats. In regions with harsh winters, they may not survive and return each year, but in milder climates, they can re-emerge. For best results, they are often grown as annuals, with new bulbs planted each spring for vibrant blooms.
