We have a plant cluster about 14-15 years old and it has not flowered for the past 2 years. The center of the plant has died out and been removed, leaving a ring of plants about 18-20 in diameter. It flowered beautifully foe the first 12-13 years but has stopped producing. Do I need to remove it completely and replace it, or perhaps some fertilizer? Leaf growth seems OK, 15-20 clusters of leaves about 12-14 inches tall. Thanks for your help.

I have seen perrenials get attacked from under the bulb by insects. They will not flower again and the plant will soon die. See if you can pull it up easily. If you can, it's gone. If not,cut it back all the way to 2 inches in the fall. This should stimulate new growth and hopefully new flowers in the spring.
