Polyscias scutellaria 'Fabian'

Identity and naming history of Polyscias scutellaria 'Fabian'

'Fabian' has been sold under several Polyscias names over the years, including Polyscias scutellaria 'Fabian', Polyscias balfouriana 'Fabian' and Polyscias 'Fabian'. Its original breeder and exact species identity remain uncertain.

Polyscias scutellaria is associated with wet tropical conditions and has long been grown in New Guinea, the Solomon Islands, Vanuatu and other parts of the western Pacific.

Caring for Polyscias scutellaria 'Fabian'

• Roots and watering: let the upper part of the mix dry and check that the pot feels lighter before watering thoroughly. Let all excess water drain away.
• Light: bright indirect light supports compact leafy growth around the trunk. Once Fabian has adjusted to its position, some gentle morning or late-day sun is fine. If midday sun is strong, use a sheer curtain or move the plant a little farther from the window.
• Branching and handling: tip pruning can encourage side buds to grow into new branches. Support the woody stem when moving or pruning a larger plant to protect the crown.
• Potting mix and repotting: use a loose, organic-rich potting mix with bark, perlite or another chunky ingredient for drainage. Move to a slightly larger pot when roots fill the container, watering becomes unusually frequent, or the mix has become compacted.
• Temperature and humidity: keep Fabian around 18–27 °C with moderate humidity. Choose a position away from cold draughts and direct hot air.
• Feeding: feed lightly with a complete fertiliser while new leaves are forming; use the label for dose and frequency. If growth pauses, wait until new leaves appear before feeding again.

Common issues with Polyscias scutellaria 'Fabian'

• The crown opens and new stems stretch: insufficient light is stretching the new growth. Move Fabian gradually to a brighter spot with filtered light. Once new shoots grow with shorter gaps between the leaves, trim stretched stems if you want to reshape the crown.
• Leaves are shed soon after a move: Fabian can react to sudden changes in temperature, light or watering. Set it in a warm spot with bright filtered light and let the upper mix partly dry before the next watering.
• Leaf margins turn crisp: repeated drought, dry heater air or a cold draught can damage the edges. Water once the upper mix has partly dried, keep the plant away from heating vents and maintain a steady room temperature.
• Lower leaves yellow while the root ball remains wet: the mix is drying too slowly and stressing the roots. Let it dry further between waterings and check the drainage. If roots are dark and soft, trim back to firm healthy tissue with a clean tool, discard the rotten material and repot into fresh freely draining mix.
• Brown bumps, cottony clusters or fine pale speckling appear: brown bumps indicate scale, cottony deposits suggest mealybugs, and fine pale speckling or webbing points to spider mites. Move the plant away from others, then use a treatment labelled for the pest you identify. Follow the repeat schedule printed on the label.

Polyscias scutellaria ‘Fabian’ is toxic to cats and dogs

• Keep this plant away from cats and dogs that may chew it.
• It contains saponins that can irritate the mouth and digestive tract.
• Chewing may cause drooling, vomiting, stomach pain, reduced appetite or weakness. Contact a veterinarian if symptoms develop.

About the name Polyscias scutellaria

Polyscias combines Greek polys, many, with skia, shade, parasol or canopy. The epithet scutellaria comes from Latin scutella, meaning a small dish, saucer or shield.

Johann Reinhold Forster and Johann Georg Adam Forster established the genus Polyscias in 1776 in Characteres Generum Plantarum, second edition, page 63.

Nicolaas Laurens Burman first described it as Crassula scutellaria in 1768 in Flora Indica, page 78. Francis Raymond Fosberg later placed it in Polyscias as Polyscias scutellaria in 1948 in Occasional Papers of the University of Hawaii, volume 46, page 9.
