Answer: I wouldn't give up on them just yet. Artichokes can fail to flower if the weather gets too hot while the flower stalks are beginning to form. It's possible that your young plants simply couldn't muster the energy to produce flowering stalks due to weather or immaturity or even lack of cold temperatures the winter prior to your planting. I'd give them another chance to perform. Frostbitten foliage can be cut away from your plant this winter, to make room for healthy new growth this spring. Be sure to keep your artichoke plants well watered during the growing season and make sure they're planted in full sunshine. I'll bet yours will flower this year.
