Knowra Dracaena trifasciata Dracaena trifasciata Dracaena trifasciata is a tropical West African flowering plant with stiff, upright, sword-shaped leaves. It is widely grown as an ornamental houseplant and was formerly classified as Sansevieria trifasciata.
Asparagaceae : Asparagaceae is a family of flowering plants that includes asparagus, agaves, and Dracaena. Modern classification places Dracaena trifasciata in this plant family.
Houseplant : A houseplant is a plant grown indoors, typically for decoration or enjoyment. This species is among the most widely grown indoor foliage plants.
Crassulacean acid metabolism : Crassulacean acid metabolism is a photosynthetic pathway that takes in carbon dioxide mainly at night to conserve water. This pathway helps the plant limit water loss in dry conditions.
Dracaena angolensis : Dracaena angolensis is a related African species with cylindrical, upright leaves. Its round leaves distinguish it from the flat, sword-shaped leaves of this species.
NASA Clean Air Study : The NASA Clean Air Study investigated whether houseplants remove indoor air pollutants in sealed chambers. Its results are often cited to claim this species cleans indoor air.
Dracaena : Dracaena is a genus of flowering plants, many of which are cultivated as ornamentals. Molecular classification moved this species from Sansevieria into Dracaena.
Plant propagation : Plant propagation is the production of new plants from seeds or vegetative material. The species is commonly multiplied by division, leaf cuttings, or seed.
Stomata : Stomata are adjustable pores in plant surfaces that regulate gas exchange and water loss. Their nighttime opening supports carbon uptake while reducing daytime transpiration.
Dracaena masoniana : Dracaena masoniana is a West African species with broad, paddle-shaped leaves. Its broad blades contrast with the narrow upright leaves typical of this species.
Indoor air quality : Indoor air quality describes the physical, chemical, and biological conditions of air inside buildings. The plant's real-world effect on room air is much smaller than popular claims suggest.
