Ask The Plant Expert:

My Peace plant flower is green, it should be white. What does it need?

Flower Shop Network Plant Expert Reply:

Could be a variety of things. What most people call the the bloom is actually called a spathe. This is sort of like a leaf and surrounds the spadix, which supports the actual flowers of the plant. The Spathes can range in color from a pure white to a pale whitish green.

Factors you can work with to achieve better blooms: humidity, water light and fertilizer. Giving the plant the proper humidity and water will help make the formation of leaves, spathes and flowers stronger. The right fertilizer and light will help with strength the color and structure of the plant. So, follow the care instructions for Peace Lilies (at the bottom). Hopefully this will change future spathes from green to white.

Hope this is helpful!
