Copperleaf (Acalypha wilkesiana) - How to Grow & Care Guide

Plant Snapshot

Common Name: Copperleaf
Latin Name: Acalypha wilkesiana
Hardiness Zones: USDA zones about 10–11 in frost free locations. Often grown in containers or as an annual where colder.
Typical Height: About 3–6 ft (91–183 cm) at maturity depending on cultivar and pruning.
Typical Spread: Typically 3–6 ft (91–183 cm) wide, forming a bushy shrub or hedge.
Bloom Period: Small inconspicuous flower spikes appear mainly in warm months and can be produced year round in frost free climates.
Soil Preferences: Fertile, consistently moist and well drained soil. Tolerates average garden soils. Avoid waterlogged or very dry soils. Prefers slightly acidic to neutral pH around 6.0–7.5.
Light Preferences: Bright filtered sun to part shade. Can tolerate full sun in tropical climates if watered. Intense direct sun may scorch foliage.
Toxicity: Sap can irritate skin and eyes. Ingestion may cause gastrointestinal upset in people or pets. Confirm toxicity details with local poison control or veterinary sources.
Propagation: Easily propagated by tip or softwood stem cuttings. Seed is possible but cultivars are commonly propagated vegetatively.

Copperleaf (Acalypha wilkesiana) is a tropical evergreen shrub prized for bold copper bronze and variegated foliage. It is normally grown as a multi stemmed shrub or clipped hedge in frost free sites and works well in containers or as an annual where freezes occur.

Identification

Copperleaf is grown for colorful leaves rather than flowers and shows copper bronze red or variegated foliage depending on the cultivar. Plants typically form a bushy habit about 3 to 6 feet tall and wide. Flowers are small inconspicuous spikes and the sap can irritate skin or eyes.

Where to grow and common uses

Best suited to warm frost free climates USDA zones about 10 to 11 where it remains evergreen and vigorous. Use as a specimen shrub mass planting or clipped hedge. In cooler regions grow in containers move indoors or treat as an annual to avoid cold damage and winter loss.

Planting and spacing

Plant at the same soil depth as the nursery pot and position to allow mature spread which commonly ranges from 3 to 6 feet. For hedges space plants to match the expected spread. In colder areas plant after risk of frost has passed or keep in containers for easy relocation.

Light water and soil

Provides best foliage color in bright filtered sun to part shade and tolerates full sun when warm and consistently watered. Prefers fertile moist well drained soil with a slightly acidic to neutral pH around 6.0 to 7.5. Avoid waterlogged soil and extended drought which reduces leaf quality and vigor.

Pruning and after flowering care

Responds well to regular pruning and shaping and is commonly trimmed into formal hedges or kept compact by cutting back shoots. Remove frost damaged stems promptly to encourage new growth. Prune to control spread maintain density and refresh foliage as needed through the growing season.

Propagation

Root tip or softwood stem cuttings readily and are the usual method to propagate cultivars true to type. Cuttings root quickly under warm humid conditions. Seed is possible but may not produce plants identical to the parent cultivar so vegetative propagation is preferred for named varieties.

Safety and maintenance

The sap can irritate skin and eyes and ingestion may cause gastrointestinal upset in people or pets. Handle cut stems with gloves and keep plants away from young children and curious pets. Monitor for general garden pests and maintain good hygiene to reduce stress on the plants.

Frequently asked questions

How fast does Copperleaf grow?: Growth rate varies by cultivar site and care. In warm frost free climates plants often grow vigorously and reach the typical mature size of about 3 to 6 feet given good light moisture and fertility.
Is Copperleaf frost hardy?: No it is tender and best in USDA zones about 10 to 11. In colder areas grow in containers or treat as an annual to avoid cold damage and winter loss.
How do I propagate Copperleaf?: Use tip or softwood stem cuttings which root readily under warm humid conditions. Vegetative propagation preserves cultivar traits better than seed.
Can Copperleaf be used as a hedge?: Yes it is commonly grown as a multi stemmed clipped hedge. Space plants to match the 3 to 6 foot mature spread and prune regularly to maintain shape and density.
Is Copperleaf toxic?: Sap can irritate skin and eyes and ingestion may cause stomach upset. Confirm specific toxicity details with local poison control or a veterinary source before planting near children or pets.
