I saw a post with someone who had fire witch dianthus on a Pennsylvania gardening page. It looked great in the pic. People were saying how much they liked it. I stumbled upon some today. Tell me about your experience with it. In the past I avoided dianthus because it’s a plant I commonly see for sale but rarely see thriving year after year in peoples gardens. For those who have it what have you found to be the ideal spot for it to thrive ? I am in zone 7a Philadelphia
