Acalypha Care & Identification Guide

Acalypha (Acalypha wilkesiana), commonly known as Copperleaf or Jacob's Coat, is an exceptionally colorful, evergreen tropical shrub native to the sun-drenched islands of the South Pacific. Highly prized in tropical landscaping for its stunningly colorful foliage, it features large, heart-shaped coppery-red and bronze leaves decorated with finely serrated, bright rose-pink margins. Botanically, it is a highly heat-loving plant that synthesizes high concentrations of anthocyanin pigments to protect its cellular structures from intense tropical sun. TOXICITY WARNING: Acalypha contains toxic saponins and tannins in its milky sap, which causes gastrointestinal irritation, drooling, and vomiting if chewed or ingested by household pets.

Complete Care & Cultivation Guide

Follow our detailed scientific care guide to keep your Acalypha thriving and gorgeous all year round.

💧 【Watering & Moisture】 Water regularly to keep the soil consistently moist but never soggy. Copperleaf loves high humidity and consistent root moisture; do not let the soil dry out completely.

✂️ 【Pruning & Grooming】 Prune in late winter or early spring to control its fast growth and promote dense, colorful branching. Wear gloves to avoid mild skin irritation from its milky sap.

🧪 【Fertilization】 Feed monthly during spring and summer with a balanced organic liquid fertilizer to support its rapid growth and stimulate the production of intense leaf colors.

☀️ 【Sunlight & Exposure】 Thrives in full sun to bright, filtered indirect sunlight. Full sun is absolutely essential to produce the most intense, glowing coppery-red and rose-pink foliage colors.

🪴 【Ideal Soil Mix】 Requires rich, fertile, organic-rich, and well-draining soil. A mix of 40% composted organic loam, 40% peat moss, and 20% perlite is ideal to retain moisture while draining excess water.

🌱 【Propagation】 Propagated easily from softwood stem cuttings in summer. Dip cuttings in rooting hormone, plant in a moist peat-sand mixture, and keep warm and under high humidity.

🌡️ 【Temperature & Ventilation】 Strictly tropical. Thrives in temperatures between 16°C and 32°C (60°F - 90°F). Highly sensitive to frost and cold drafts; drops leaves if temperatures fall below 12°C (55°F).

🏺 【Potting & Container】 Perfect as a high-contrast container plant outdoors or in bright sunrooms. Use deep, wide terracotta pots with ample drainage holes and keep the soil evenly moist.

🐛 【Common Pests】 Susceptible to whiteflies, spider mites, and mealybugs in hot, dry weather. Spray the leaves regularly with organic neem oil and maintain good air humidity.

🦠 【Common Diseases】 Prone to root rot in waterlogged soils, and powdery mildew under poor air circulation. Ensure excellent ventilation around the foliage.

🎓 【Botanist Advice】 The species name 'wilkesiana' honors Admiral Charles Wilkes of the US Navy, who collected this beautiful plant in the South Pacific during his famous exploring expedition in the 19th century.

Frequently Asked Questions

Why are the leaves of my Acalypha (Copperleaf) turning green?

A loss of copper and pink colors is almost always caused by insufficient light. Acalypha requires full sun or very bright indirect light to produce the colorful pigments; move it to a brighter location.

Is Acalypha toxic to dogs and cats?

Yes. Acalypha wilkesiana leaves contain toxic saponins and tannins. Chewing the foliage can cause oral irritation, drooling, vomiting, and gastrointestinal inflammation in pets.

How fast does Acalypha grow?

It is an exceptionally fast-growing shrub in warm climates, easily growing 3 to 5 feet tall and wide within a few seasons if provided with ample sunlight, warmth, and regular watering.

Does Copperleaf produce flowers?

Yes, but they are very small and insignificant, forming narrow, drooping greenish-pink catkin-like spikes that are hidden behind the spectacular colorful foliage.
