Heptapleurum actinophyllum 'Golden Amate'

Where the species behind Heptapleurum actinophyllum 'Golden Amate' grows naturally

Heptapleurum actinophyllum is native to southern New Guinea and northern Australia. In the wild it occurs in warm, humid tropical forest, including wet lowland areas, and can also grow on trees.

How to care for Heptapleurum actinophyllum 'Golden Amate'

Keep ‘Golden Amate’ in bright filtered or indirect light. Good light supports strong growth and its yellow-green colour, but pale foliage can scorch if the plant is moved straight into intense sun. Introduce any direct sun slowly.

Warmth and humidity. Keep temperatures around 18–24 °C and avoid prolonged temperatures below 10 °C. Aim for 50–60% humidity. This plant appreciates humid air, especially as it becomes large. Keep it away from constant dry heat and sudden cold air; a humidifier can help in an extremely dry room.

Potting mix. Use a loose, well-draining mix that holds some moisture.

Water when the potting mix has dried partway and the pot feels noticeably lighter. Rewater before repeated wilting, let excess moisture drain after thorough watering and avoid keeping the roots constantly wet.

Feeding. Feed while new leaves are growing. Once growth pauses, cut back on fertiliser.

Repotting. Use a larger pot when roots are crowded. Replace compacted mix without increasing pot size when roots still have room. A top-heavy plant may need a heavier outer pot or a stem support.

Support and pruning. Support a tall stem when needed. To reduce height and encourage branching, cut just above a leaf joint.

Common problems with ‘Golden Amate’

• Patchy bleached or dry brown marks appear on the side facing the window: This is different from the plant’s naturally even yellow-green colour and usually points to sun scorch. Move it back from strong direct sun and increase exposure more gradually next time.
• Leaves yellow, droop or fall: Check the potting mix throughout the pot. Let a wet, heavy pot dry further; water a dry, light pot thoroughly. If the roots are soft and dark, use the root-rot guide before removing any damaged roots.
• New leaves are smaller and the stems are becoming more open: Move the plant into brighter indirect light first. Reassess feeding only once it is growing well again; fertiliser will not solve a shortage of light.
• White cottony clusters or sticky patches appear: Check the leaf stalks and stem joints for mealybugs. Set the plant aside from the rest of your collection, remove visible insects and choose a treatment labelled for mealybugs on houseplants if needed. Repeat it in line with the label instructions. The mealybug guide explains the treatment steps.

Heptapleurum actinophyllum ‘Golden Amate’ is toxic to people and pets

• Keep this plant away from children, cats and dogs.
• Its leaves and stems contain insoluble calcium oxalate crystals, which can irritate the mouth, throat, skin and eyes.
• Chewing may cause burning pain, drooling, swelling, vomiting or difficulty swallowing. Contact a veterinarian or medical professional after exposure, especially if swelling or breathing problems occur.

How did the name change from Schefflera actinophylla to Heptapleurum actinophyllum?

Heptapleurum combines Greek hepta, meaning seven, with pleuron, meaning rib or side. The epithet actinophyllum means ray-leaved.

Joseph Gaertner established the genus Heptapleurum in 1791 in De Fructibus et Seminibus Plantarum, volume 2, page 472.

Stephan Friedrich Ladislaus Endlicher first described it as Brassaia actinophylla in 1839 in Novarum Stirpium Decades, volume 1, page 89. Porter Prescott Lowry and Gregory M. Plunkett later placed it in Heptapleurum as Heptapleurum actinophyllum in 2020 in Novon, volume 28, page 146.

Schefflera actinophylla is the familiar former name. Porter P. Lowry II and Gregory M. Plunkett reinstated Heptapleurum for the Asian group formerly included in Schefflera in 2020 in Novon, volume 28. Kew’s World Checklist accepts Heptapleurum actinophyllum.
