People sometimes call begonias the angel wing begonia in general, but Begonia Julau is the one I personally would prefer to call the butterfly wing begonia. Begonia Julau's foliage color changes based on maturity, the younger the pinker, the older the greener. The third photo is a good example of a mother plant that contains both young and mature foliage. It's a relatively easygoing plant for terrarium plant beginners, yet can easily take people's breath away.
