Q.

Calla lily color change

Zone Garden zone 9 | Anonymous added on July 3, 2018 | Answered

I have two large groups of calla lilies planted in my flower beds that have been there for over 10 years. One group is white and the other is yellow, at least until this year. This spring I needed to divide the bunches and move them within the same flower bed. They transplanted fine but now both groups have changed color. Where the white ones were the new flowers this year are coming out yellow and the ones that were yellow are coming out light pink. I have seen several other postings that ask about the colors changing but the answers seem to say that it cant happen or its because there were multiple colored bulbs in the pot and when they were planted a different color bulb became dominant. Mine have been in the same place in my yard to over ten years and have never had a color change until this year. The only two things that are different about this year is that we had an exceptionally cold and long winter this year and of course the fact that they were divided and moved. Can anyone explain this?

If your lily's flowers are changing color, it could be a normal part of the plant's life cycle, or it could indicate an environmental problem.
Too little light will result in fading of lilies' flowers. If your calla lilies are indoors, move them to a room that receives brighter natural light, or supplement the sunlight by placing the lilies underneath a plant light. Make sure the room is warm enough and that no cold drafts affect the plant.
Conversely, calla lilies planted outdoors will fade and turn yellow if placed in too hot or bright a location. Move lilies to an area with full or partial shade to prevent burning and fading of flowers and foliage.
