I have a peace lily which is thriving with lots of new leaves and flowers sprouting almost daily. However, the older flowers have turned from white to green and the yellow seed bit has gone dark green. Have they reached the end of their life, and should I cut them off?
Why Have Flowers Gone Green on My Peace Lily

When the flower first forms it is usually green like the rest of the leaves. As it opens it turns from green to white.
As the bloom ages it takes on a more green shade again and eventually will turn completely green.
The color change is due to chlorophyll. Because the flower is actually a form of leaf. The process of photosynthesis takes place and the flower absorbs the sunlight and turns green.
When the flower collapses you can cut it off.
