why has my Peace Lily gone green instead of white?
Answers:
New flowers start green and mature to white, If they do not mature, then it is probably a problem with light levels or water; keep the plant out of direct sunlight - half shade is best - and keep the compost moist, but don't let the roots sit in water. To get the most flowers the plant should be relatively potbound - ie the roots should fill the pot and be busting out before you repot (too much compost around the roots makes the plant lazy and it will only make new leaves!)
Hope this is of some use!
