Growing season in north Florida

Question

Dianthus grow from May to October and frost would do them in. Is that applicable for north Florida? They are abundant at Home Depot and Lowes but I was hesitant to buy them. Will they make it until January? No photos.

Answer 1

In north Florida, you would most likely have your first frost sometime in December. Most Dianthus flowers can withstand a light frost but not a hard frost. So they would most likely make it to December, but it's hard to predict whether they'd make it to January.
