I have 2 of the above plants. I potted them instead of planting in ground. They have not flowered all summer. Do you know of any reason why? They are in a part sun, part shade area and are well watered.

This could be a nitrogen issue, if the soil you used contained a fertilizer or if you have over fertilized. Too much nitrogen will inhibit flowering. You can add phosphorous by using Bone Meal.
