Camphor Tree (Cinnamomum camphora) - How to Grow & Care Guide

Plant Snapshot

Common Name: Camphor Tree
Latin Name: Cinnamomum camphora
Hardiness Zones: USDA zones 9–11 typical. May survive marginally colder sites with protection.
Typical Height: 40–100 ft (12–30 m).
Typical Spread: 30–60 ft (9–18 m) canopy spread.
Bloom Period: Spring blooms, typically Mar–May in the Northern Hemisphere.
Soil Preferences: Prefers fertile moist well drained soil but tolerates clay, sand, and coastal soils. Poor drainage can cause root decline.
Light Preferences: Full sun to partial shade. Best canopy development in full sun.
Toxicity: Contains camphor which is toxic if ingested and can irritate skin. Ingestion can be dangerous to children and pets.
Propagation: Seed, semi hardwood cuttings, and air layering are used for propagation.

Key Facts

Evergreen broadleaf tree native to East Asia.
Leaves and wood produce aromatic camphor oil.
Small white fragrant flowers appear in spring.
Produces small black drupes eaten and dispersed by birds.
Can grow into a large shade tree with a wide canopy.
Tolerant of a wide range of soils and coastal exposure.
Considered invasive or weedy in some subtropical regions.
Can be toxic if large amounts of camphor are ingested.

Camphor is an aromatic evergreen broadleaf tree grown for shade and the camphor in its leaves and wood. It makes a large, long-lived specimen but can naturalize and spread in warm coastal and subtropical landscapes.

Identification

Evergreen tree with glossy leathery leaves that release a strong camphor scent when crushed. Clusters of small creamy white fragrant flowers appear in spring followed by small black drupes eaten and dispersed by birds. Mature bark becomes furrowed on older specimens and the canopy is rounded to broadly spreading.

Best uses and where to grow

Used as a large shade or specimen tree in parks and spacious yards where USDA zones 9 to 11 conditions are available. It tolerates coastal exposure, a wide range of soils and urban conditions. Avoid planting where spread and naturalizing are concerns because it is considered invasive in some subtropical regions.

Planting and spacing

Choose a permanent planting spot with room for a wide canopy. Mature spread commonly reaches 30 to 60 feet so space new trees at least that far from buildings and other large trees to avoid competition and future pruning. Plant during a mild season so roots can establish before extremes of heat or cold.

Soil light and watering

Prefers fertile, moist, well drained soil but tolerates sand, clay and a wide pH range if not waterlogged. Grow in full sun to partial shade for best canopy development. Avoid poorly drained sites because waterlogged soils increase the risk of root decline and overall decline in tree health.

Growth size and rate

Mature height typically ranges from about 40 to 100 feet 12 to 30 meters with a broad canopy often 30 to 60 feet across. Growth is faster in warm, favorable sites and slower with cold stress or limited root space. Urban or stressed trees frequently remain smaller than specimens in optimal conditions.

Flowering and fruit

Produces clusters of small creamy white flowers in spring typically from March through May in the Northern Hemisphere. Flowers are fragrant and give way to small black drupes that attract birds which help disperse seed and contribute to naturalizing populations.

After-flowering care and pruning

Prune to remove dead wood and to shape the canopy while the tree is young to limit eventual width. Regular pruning can reduce suckering and lower limbs that interfere with structures. Avoid excessive root disturbance and heavy pruning on older trees which can stress the tree and invite decline.

Containment and invasiveness

Camphor Tree naturalizes where conditions are warm and birds disperse seed. It is considered invasive or weedy in some subtropical regions and may form seedlings downwind of parent trees. Check local extension or invasive species authorities before planting and remove seedlings promptly to limit spread.

Propagation

Propagate by seed or vegetative methods such as semi hardwood cuttings and air layering. Seedlings may not come true to a named cultivar so use cuttings or layering to clone desirable specimens. Allow newly planted material adequate moisture and protection until roots establish.

Toxicity and safety

Contains camphor and related compounds that can be toxic if large amounts are ingested and may irritate skin or mucous membranes. Plant parts and oils can be harmful to children and pets. Verify emergency guidance and toxic dose information with local poison control or veterinary resources if ingestion is suspected.

Frequently asked questions

How fast does Camphor Tree grow?: Growth rate varies by climate and site. Trees tend to grow faster in warm, favorable locations and more slowly where winters are colder or soils are poor.
Is Camphor Tree invasive?: It is considered invasive or weedy in parts of the subtropics where seedlings naturalize. Confirm local status with extension services and remove volunteer seedlings to limit spread.
Can I plant a Camphor Tree near my house?: Give it ample room. Mature trees commonly reach 30 to 60 feet wide so plant well away from foundations, driveways and utilities to avoid conflicts as the canopy and roots expand.
How do I propagate Camphor Tree?: Use seed for general stock or semi hardwood cuttings and air layering to clone specific trees. Vegetative methods preserve the parent plant traits.
Are camphor leaves or oil poisonous to pets?: Plant material and concentrated oils containing camphor can be harmful to pets if ingested. Contact a veterinarian or poison control for guidance if exposure is suspected.
