I was given a white Calla Lily recently, which I have kept in a pot placed on a window sill that gets some morning sun. I have noticed that in the past week the white flowers have now turned green on the outside. Is this normal? The plant is very healthy. I would love to know if this is normal.
There's no need to worry about the green color. These flowers do that as they mature and begin producing seeds. You can cut them off or leave them be.
