- Tropical evergreen commonly grown as a houseplant
- Native to tropical central and eastern Africa
- Has cane like stems with arching lanceolate leaves
- Prefers bright indirect light but tolerates lower light

- Toxic to dogs and cats if ingested causing vomiting and drooling
Corn plant is a tropical evergreen commonly grown as an easy care indoor specimen with cane like stems and arching lanceolate leaves. It is used as a tall architectural houseplant or in sheltered subtropical landscapes but it is toxic to dogs and cats if eaten.
Identification
Cane like woody stems carry clusters of arching, lance shaped leaves. Mature plants sometimes produce fragrant clusters of white to pale pink flowers, though blooms are uncommon on indoor specimens. The species is native to central and eastern Africa and is often sold under the name mass cane.
Where to grow Corn plant
Best used as a floor plant in homes and offices where it provides vertical structure and a tropical look. In frost free, subtropical areas it can be grown outdoors in the landscape or in large containers. Outdoors it is suitable to USDA zones 10 to 12, while in cooler climates it is normally kept as a container houseplant.
Light and location
Bright filtered light is ideal. The plant tolerates lower light but growth slows and variegation may fade. Avoid strong direct sun which can scorch leaves.
Soil and potting
Use a loose, well draining potting mix that is rich in humus. A slightly acidic to neutral pH around 6.0 to 7.0 suits most specimens. Avoid waterlogged soil because poor drainage encourages root rot.
Watering and feeding
Allow the potting mix to dry slightly between waterings and reduce water when growth slows in lower light. Overwatering leads to root rot and shows as yellowing leaves and soft stems. Underwatering causes brown leaf tips and slowed growth. Feed lightly during the active growing season on a schedule suited to your fertilizer product.
Containers and pruning
Corn plant adapts well to pots. Repot into the next size up when the root ball becomes dense. Prune stems to control height and to create branching. Cut cane sections can be rooted to make new plants.
Propagation
Propagate by stem cuttings, cane sections or air layering. Cane sections and cuttings root readily in water or in a free draining, moist rooting medium.
Flowering and after flowering care
When flowers appear they form fragrant clusters but flowering is rare indoors. Remove spent flower clusters and continue standard care. Flowering does not usually require special follow up beyond normal watering and feeding adjustments.
Controlling spread and landscape use
Mature plants form a clump or a single cane canopy that commonly spans about 2 to 4 feet depending on stems and pruning. It is not generally considered invasive and is easy to keep contained by growing in a pot or by cutting back stems.
Toxicity and safety
Dracaena fragrans is toxic to dogs and cats. Ingestion commonly causes vomiting, drooling and lethargy. Severity depends on animal size and the amount eaten. Handle sap carefully to avoid skin or eye irritation and consult pet poison control or the ASPCA for clinical advice if needed.
Frequently asked questions
- How fast does Corn plant grow?
- Growth varies by light, pot size and cultivar. Indoors growth is generally moderate to slow and many specimens reach roughly 3 to 10 feet over several years depending on care and pruning.
- Is Corn plant safe for pets?
- No. It is toxic to dogs and cats and can cause vomiting, drooling and lethargy. Contact pet poison control for guidance after ingestion.
- Will Corn plant flower indoors?
- Flowering is occasional and rare in typical indoor conditions. When it does bloom the flowers are fragrant and form in clusters.
- Can I grow Corn plant outdoors?
- Yes in frost free subtropical gardens. Outdoor hardiness is generally given as USDA zones 10 to 12. In cooler climates it is best grown in a container and brought indoors for cold weather.
- How do I propagate Corn plant?
- Use stem cuttings, cane sections or air layering. Cuttings root readily in water or a moist, free draining potting mix.
