I just purchased a number of dianthus carnation plants and was wondering if I can permanently plant them in my zone 5-6 garden without worrying that they might not make it through the winter, or should I plant them in pots and then protect them over the winter? I've come across conflicting information on this subject. I don't know the specific name of the variety, but they are doubles and resemble the florist type but are much smaller flowers on medium length stems with moderate fragrance.

The type you describe are perennial hardy to zone 3, so you can plant them right in the garden. They do best in a rich, well-drained soil of near-neutral pH. Despite their hardiness, they're not long-lived, so you'll need to plant new ones every 2-3 years for a reliable display. Enjoy!
