Anemone De Caen, also known as windflowers, are considered perennial plants, meaning they have the potential to come back every year. However, their level of hardiness varies depending on the climate.
In milder climates, such as USDA hardiness zones 5 and up, Anemone De Caen can reliably return each year without needing to be lifted and stored during the winter months.
In colder climates, where the ground freezes, these bulbs may not survive the winter, and it is recommended to lift and store them in a cool, dry place to replant in the following spring. Providing proper care, such as adequate watering and fertilization, will also encourage healthy growth and return.
