Once again the office surrounds... I think this peace lily is a little greenish due to lack of sunlight. Today is the winter solstice (shortest day of the year for the southern hemisphere), so it can only improve from here!
I love these plants, Madonna Lillies are one of my favourite indoor plants, nice composition, and yes it is lucky it was the shortest day of the year because it certainly was one of the most miserable weatherwise :)
Your shortest day, our longest day, it will be all down hill for us now, don't like the dark nights or mornings.....
