Lucky Bamboo
Dracaena sanderiana · Ribbon Dracaena
It grows in the shaded, humid understory of West-Central African rainforest, an erect herb with slim jointed green stems. It is not bamboo at all. It is a Dracaena, the same genus as the snake plant, trained into spirals and braids and sold in a glass of water.

Where it's from
West-Central tropical Africa
African, not Asian
Native to Cameroon and the Congo region, extending to northeast Angola. The names 'Chinese' and 'bamboo' are both misnomers.
A fleshy stem
Its jointed green stems read as bamboo canes, but they are fleshy, not woody and hollow like a true bamboo grass.
Outdoors: zones 10–12
Frost-free tropics only, where it grows as a shaded understory plant. A houseplant everywhere colder.
Not bamboo at all
Lucky bamboo is a West African rainforest Dracaena, the same genus as the snake plant, sold in a glass of water as a feng-shui good-luck charm. The famous spiral isn't a cultivar, it is the plant being rotated toward the light for months so it grows in a curl. The braids, hearts and lattice towers are all grower training, not genetics.
Lives in plain water
It roots and grows indefinitely in a dish of pebbles and water, no soil required, which is exactly how it is sold.
Shaped, not bred
Spirals, braids and towers are months of training stems toward light and wiring frames.
Rarely flowers indoors
Small white flower clusters appear in the wild, but it essentially never blooms as a houseplant.
How to keep it
LightBright, indirect
Filtered light, tolerating part to deep shade. Direct sun scorches the leaves and low light fades the colour.
WaterGrows in water
Keep one to two inches of water over the roots and change it every one to two weeks. In soil, keep evenly moist.
HumidityAverage is fineTolerates dry household air, but does best in higher humidity.
Temperature16–27°CWarm. Keep above about 10°C and away from cold drafts. No frost.
SoilWater and pebblesUsually grown in water with a pebble anchor. In soil, a rich, well-draining loam.
FeedingBarelyA few drops of dilute feed every couple of months. Salt buildup browns the tips, so under-feed.
DifficultyVery easyOne of the most beginner-proof houseplants there is.
With petsToxicSaponins. Vomiting, depression, loss of appetite, drooling and dilated pupils in cats if chewed.
PropagationStem cuttingsCut a healthy stem above a node and root it in water. The cut parent re-sprouts below the cut.
RepottingRarelyMostly just topping up and changing the water. Refresh the dish every couple of years.
What the data says
What it costs
One of the cheapest, most-gifted houseplants on earth. The price climbs with the shaping, not the plant.
$3–25
Elaborate spirals and tall braided towers run $30 to $100 or more, but that is labour, not botanical rarity. Variegated forms carry no premium.
The air-purifier claim
Dracaena starred in the NASA study, but that result came from a sealed lab chamber.
100–1,000
plants per square metre would be needed to match a room's normal ventilation (Cummings and Waring, 2019). NASA's 1989 test used a sealed box with no airflow. Keep it for the looks and the symbolism.
IUCN · Not assessed
In the wild
Abundant in commerce, barely tracked in nature, while its dragon-tree cousins are the ones at risk.
Dracaena sanderiana is not assessed on the IUCN Red List, and the houseplant trade is supplied almost entirely by cultivation, not wild collection. The genus's real conservation tension sits with relatives like the dragon's-blood trees D. draco, D. cinnabari and D. ombet, which are Red-Listed and threatened.
When it sulks
Brown, crispy leaf tipsThe signature complaint. Chlorine, fluoride or salts in tap water, fertilizer buildup, or low humidity. Switch to distilled or rain water.
Yellow stems or leavesToo much direct sun, too much fertilizer, or stale water. Refresh the water and move out of direct light.
Mushy base, smelly waterRot from stagnant or rarely-changed water, or overwatering in soil.
Floppy, top-heavy stemsNormal as tall stems add weight. Support or trim them.
PestsMealybugs, spider mites and scale.
