Can dianthus stay outside in winter?

Dianthus, commonly known as carnations or pinks, can generally tolerate winter conditions, especially in milder climates. Many varieties are hardy and can survive winter temperatures, particularly if they are well-established and planted in well-drained soil. However, in regions with harsh winters, they may require some protection, such as mulch, to prevent frost damage. Always check the specific hardiness zone for your dianthus variety to ensure proper care.
