Hello everyone! I purchased a peace lily 'Domino' from Trader Joe's a little while back and was wondering what causes the variegation in this specific cultivar. I have done some research but there is not much information about it. The leaves have a bumpy texture and the stems and spathes are variegated as well. There are a few other variegated peace lilies out there such as peace lily 'Sensation Variegated' and peace lily 'Picasso,' but when I looked up pictures of them neither of them have bumpy leaves like the peace lily 'Domino.' Any knowledge would be appreciated.

Thank you!
