Tree lilies two different colours

Question

I have red tree lilies in flower planted in pots last year all flowered last year, this year all in red flower with side shoots come up in flower put they are white flowers, why?

Answer 1

Your lily may have mutated. Random mutations happen during cell division and replication, after exposure to radiation or because of weather extremes. Or it could have reverted to one of its parent's characteristics. If you don't like the white, you can prune it out.
