I have potted calla lilies that are blooming in big clusters. One flower has a large bunch in the center of it, which then blooms into multiple flowers. Has anyone seen this before? I have pictures if needed.

This is a condition called a fused blossom or fasciated blossoms. It is kind of like the siamese twins of the plant world. It can be cause by several things - from bacteria to just plain mutation. In most cases, while the flowers look odd, it is not harmful to the plant.
