Acalypha wilkesiana: complete guide

Overview

Acalypha wilkesiana, better known as Jacob's coat, Capa de obispo, or copper-leafed acalypha, is a beautiful tropical shrub native to the Pacific region. This plant belongs to the Euphorbiaceae family. Acalypha wilkesiana is popular for its remarkable foliage variegation and compact growth habit.

The plant is known for its dramatic leaf colors varying from red to yellow, with many intermediate shades. With its tropical appearance and relatively easy maintenance, Acalypha wilkesiana is a favorite among gardeners seeking exotic colors.

Appearance and Bloom

Acalypha wilkesiana is a medium to large shrub usually reaching 1.5 to 3 meters in height. The leaves are large, wavy, and can be very colorful. The foliage ranges from red, deep red, orange, yellow to green, usually with mixed patterning.

The flowers are small and inconspicuous, though they have elongated, drooping red-pink flower spikes. The real show, however, is the colorful foliage, not the flowers. The flowers typically appear during warmer months.

Ideal Location

Acalypha wilkesiana thrives best in full sun to partial light. The plant requires at least 4-6 hours of direct sunlight daily for full color development. More sun results in richer, more saturated colors.

The plant prefers warm, sheltered locations. Wind can damage the leaves. Plant it where it receives protection from larger trees or walls. In very hot climates, light afternoon shade can be beneficial.

Soil

Acalypha wilkesiana prefers well-draining, fertile soil. A mixture of potting compost, sand, and compost is ideal. The plant tolerates a wider pH range, from slightly acidic to neutral (pH 5.5-7.5).

Well-draining soil is essential. Heavy clay soils must be improved. Regularly adding organic matter helps maintain healthy soil.

Watering

During the growing season, Acalypha wilkesiana requires regular watering. Water well, but always ensure excess water can drain away. The soil should be moist but not waterlogged.

During dry periods, extra water may be necessary. In winter, as growth slows, you can reduce watering. Once established, the plant can tolerate some drought.

Adjust watering according to weather conditions. During rainy seasons, the plant needs less water.

Pruning

Acalypha wilkesiana responds well to moderate pruning. This encourages compact, full growth. Prune best in late winter, just before active growth begins.

Remove crossing branches, dead wood, and long growers. This improves foliage colors and growth pattern. You can also lightly prune branch tips to encourage more branching.

Hard pruning can be done to keep the plant in shape.

Maintenance Calendar

Spring (March-May): Begin regular watering. Perform moderate pruning. Begin slow feeding.

Summer (June-August): Ensure adequate watering. Check for insect damage. Enjoy the colorful foliage.

Fall (September-October): Gradually reduce watering. Stop feeding. Prepare for winter.

Winter (November-February): Minimal watering. No feeding. Protect from cold.

Winter Hardiness

Acalypha wilkesiana is frost-sensitive. In zones with temperatures below 10 degrees Celsius, protection or relocation is needed. In Mediterranean zones, it can overwinter outdoors with protection.

In more temperate climates, this plant thrives best in large containers, allowing indoor relocation during winter.

Companion Plants

Acalypha wilkesiana pairs beautifully with other tropical plants. Underplant it with shade-loving structural plants. Contrast the red foliage with silver-leaved plants or with green structural plants.
