Spathiphyllum is also commonly known as a Peace Lily and has pure-looking white flowers and shiny dark green foliage. This elegant plant is one of the most popular plants to grow indoors and is super easy to look after. It is also a valuable plant as it is an efficient air purifier. Its leaves absorb toxins, mould spores, and radiation from the atmosphere, making it an ideal plant for the bedroom. The flowers produce very little pollen, so they do not aggravate allergies. The majority of Peace Lily species are native to South America.
