Stylish dark green leaves with radiant white banners floating above them and caring and communicative as well: the Peace lily is bound to steal your heart. The Peace lily has completely mastered body language. If the soil is too dry, the stems droop pitifully. If you then pour in some water, it’ll be fresh and lively again an hour later. In exchange for your good care, this houseplant also cares for you: it’s one of the plants with air-purifying qualities.
