Sansevieria Ming Manee is a relatively rare cultivar within the Sansevieria (now classified under the genus Dracaena) family, features compact rosettes of short, thick leaves. Known as some of the toughest houseplants, they store carbon dioxide acquired at night to use during the day, then releasing oxygen at night, via photosynthesis, when their pores open. This helps it to maximize efficiency in cleansing the air, as found in a study conducted by NASA.
