Why do peace lily flowers turn green? Cause analysis
1. Natural phenomenon
Peace lily flowers are white at first, gradually turn green later, and eventually become the same as the stems and leaves, while the originally yellow spadix also turns black. These are all natural phenomena of flower bloom metabolism, so there is no need to be too surprised; even when they turn green, they are still quite ornamental.
2. Light too weak
If the peace lily's spathe bud has only just opened for a few days and then turns green, that is not a normal natural phenomenon. It is caused by light that is too weak; all white flowers will show a greenish tint when light is weak. You can increase light, or apply an appropriate amount of fertilizer to supplement nutrients, and once enough nutrients have accumulated and light is sufficient, the color will change back.
