Heptapleurum (Schefflera) arboricola 'Gold Capella'

Horticultural context and species history

‘Gold Capella’ is the yellow-mottled selection that earned the Royal Horticultural Society’s Award of Garden Merit. Its long-established synonym, Schefflera arboricola ‘Gold Capella’, predates the return of the genus Heptapleurum.

The species is indigenous to Hainan and Taiwan. In humid subtropical forest, its woody branches may stand independently, scramble into surrounding vegetation or attach to tree trunks. The cultivar carries that adaptable growth habit in a smaller, golden-variegated form.

Care for healthy tropical growth

Propagation: A completely green branch may grow faster than the patterned crown and should be removed before it dominates. Use normally patterned shoots for propagation so the resulting plants retain the colouring of the cultivar.

Light: Place Heptapleurum ‘Gold Capella’ in bright filtered light for strong yellow-and-green contrast. Gentle direct sun is suitable after acclimatisation, but abrupt midday exposure can brown the pale areas.

Repotting: Let the top few centimetres of a loose, free-draining mix dry before watering the pot thoroughly. Apply a balanced feed as new growth develops and move up one pot size after roots spread through the existing container.

Plant health problems and solutions

The light-yellow margins of ‘Gold Capella’ are intentional and should not be treated as nitrogen deficiency. A single all-green shoot is a reversion and can be removed. Greener growth appearing throughout a plant kept in a dark position is more likely an environmental response to insufficient light.

Variegated sectors show sun scorch, drought, chilling and salt injury before greener tissue. Sharply bleached areas after an exposure change indicate scorch; dry brown margins across several leaves call for checks of root moisture and fertiliser residue.

Diffuse yellowing between veins on new leaves or uniform yellowing of older leaves is different from the stable cultivar pattern. Examine drainage, roots and the age of affected foliage before changing nutrition. Feeding a plant with damaged wet roots can intensify the decline.

Sooty black growth on sticky leaves indicates honeydew from scale, mealybugs or another sap feeder rather than a primary leaf disease. Find and remove the insects, then wash away the residue. Mites and thrips instead leave stippling, silver scars or dark specks.

Heptapleurum (Schefflera) arboricola ‘Gold Capella’ 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.

Why do both Schefflera arboricola and Heptapleurum arboricola appear?

Heptapleurum combines Greek hepta, meaning seven, with pleuron, meaning rib or side. The epithet arboricola means tree-dweller.

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

Bunzō Hayata first described Heptapleurum arboricola in 1916 in Icones Plantarum Formosanarum, volume 6, page 23.

Schefflera arboricola 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 arboricola.
