Heptapleurum (Schefflera) arboricola 'Gerda'

Horticultural background and plant origin

‘Gerda’ was already in European cultivation by 1994. Its cream-to-yellow central markings were therefore being maintained horticulturally more than three decades ago, before many newer named umbrella-plant selections appeared.

The wild parent belongs to Hainan and Taiwan, where Heptapleurum arboricola can grow beside streams and scramble through other vegetation. At the time ‘Gerda’ entered trade, the species was called Schefflera arboricola.

Care for healthy tropical growth

Propagation: Remove a consistently all-green branch if it begins outgrowing the patterned crown. Shorten long stems just above a node and use clearly yellow-and-green shoots for propagation so new plants keep the same markings.

Watering, root care and light: Water Heptapleurum ‘Gerda’ after the upper potting mix has dried, soaking the soil evenly and emptying the saucer or cover pot. Give a light feed while growth is active.

Light: Strong filtered light keeps the plant compact. Increase direct exposure in stages because the pale sections scorch more easily.

Recognising problems early

A whole branch becoming consistently green is a reversion in ‘Gerda’. General greener growth across the crown usually reflects low light. Remove the distinct reverted branch, but move a uniformly faded plant towards brighter filtered light before pruning.

Normal yellow-and-green markings have firm tissue and repeat in a clear pattern. Diffuse yellowing across an age group of leaves, especially with wet mix or soft roots, is chlorosis from stress rather than variegation. Correct drainage and root conditions before adding more fertiliser.

Spider mites begin as fine pale stippling that can be mistaken for the leaf pattern; webbing, progressive bronzing and activity beneath the leaf confirm the pest. Quarantine ‘Gerda’, clean both leaf surfaces and repeat treatment through the mite life cycle. Scale, mealybugs and thrips instead leave sticky residue, waxy clusters, silver scars or distorted growth. Sudden clean leaf drop without those signs may be a response to relocation.

Heptapleurum (Schefflera) arboricola ‘Gerda’ 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.

About the names Schefflera arboricola and Heptapleurum arboricola

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.
