What is a corn plant?
Corn plant (Dracaena fragrans), also sold as mass cane, is a cane-forming tropical from the asparagus family, native to tropical Africa. Indoors it grows as one or more thick, upright woody canes topped by broad arching rosettes of long, strappy leaves — often striped cream and yellow down the centre in the popular ‘Massangeana’ cultivar, giving a passing resemblance to a corn stalk, which is where the common name comes from. It is one of the most shade-tolerant and low-maintenance houseplants in cultivation, and one of the few large foliage plants that genuinely performs in genuinely low-light spaces.
How much light does a corn plant need?
Corn plant is a true low-light performer — it handles dim corners, offices lit only by fluorescent tubes, and rooms with small north-facing windows where most plants decline. It grows faster and the leaf striping of variegated forms (‘Massangeana’) stays crisper in medium to bright indirect light. Direct sun is the one thing it cannot tolerate — the broad leaves scorch and bleach rapidly in harsh exposures.
How often should you water a corn plant?
Water every 10–14 days, letting the soil dry out significantly between each session. Like its relative Dracaena marginata, the corn plant stores moisture in its thick canes and is far more forgiving of drying out than of staying wet. In winter, stretch the interval to three weeks or more. Always use filtered, distilled, or rainwater — this species is notably sensitive to fluoride in tap water.
Why does my corn plant have brown tips?
Brown tips are the corn plant’s most common complaint and almost always trace back to fluoride sensitivity. The fluoride in municipal tap water accumulates in the soil over months and damages the leaf margins from the tip inward, producing the classic tan-brown crispy edge. The fix is to switch water sources (filtered, distilled, or collected rainwater) and flush the soil every couple of months to leach minerals. Trimming the brown tips with sharp scissors does not harm the plant and improves its appearance immediately.
How do you propagate a corn plant?
Corn plant propagates easily from cane cuttings. Cut a healthy cane into sections 3–4 inches long, lay them horizontally on moist potting mix, and keep warm — shoots and roots emerge from the nodes within four to six weeks. The original stump left in the pot will also re-shoot below the cut. This is the same method used commercially to produce the multi-cane pots sold in garden centres.
Is corn plant toxic to pets?
Yes — the ASPCA lists corn plant (Dracaena fragrans) as toxic to cats and dogs. The plant contains steroidal saponins, which can cause vomiting (occasionally with blood), lethargy, drooling, and loss of appetite if ingested. Cats may also develop dilated pupils. This is a plant to keep out of reach in pet households.
