How to read these values
These care values are quick reference points for indoor growing. Use them as a guide, then adjust for pot size, substrate, temperature and how quickly the substrate dries.
For more detail, read the full product description or visit our Plant Care Guides.
- Light: level and approximate lux at leaf level.
- Watering: “% dry” shows how far the substrate should dry before watering again.
- Substrate: structure, drainage, moisture retention, base material and particle size.
- Temperature: “Ideal” shows the preferred range; “Avoid below” marks the cold-stress threshold.
- Humidity: target range; steady conditions usually matter more than exact numbers.
- Growth habit: how the plant grows, such as upright, climbing, trailing, clumping or rosette-forming.
- Support: whether a stake, pole or trellis is needed, optional or unnecessary.
- Growth speed: expected pace under suitable indoor conditions; use as a guide, not a promise.
- Max size indoors: realistic long-term indoor size under good conditions.
- Toxicity & safety: irritation, toxicity or physical hazards such as spines or bristles.
- Origin & habitat: native range, hybrid background or typical habitat where relevant.
- Outdoor growing: when a potted indoor plant can be placed outside and what outdoor protection it needs.
Polyscias guilfoylei 'Roble'
Polyscias guilfoylei 'Roble' has pinnate leaves divided into glossy, leathery, rounded leaflets. Irregular lobes and toothed edges give each leaf a defined, uneven outline on an upright woody frame.
The species grows as a shrub or treelet and can reach several metres in tropical conditions. In a pot, it stays far smaller and develops as an upright leafy shrub with a steady need for warmth, drainage and balanced moisture.
Polyscias guilfoylei 'Roble' profile
- Plant type: Woody tropical Polyscias from the family Araliaceae.
- Leaves: Pinnate leaves divided into rounded, glossy, leathery leaflets.
- Leaf edges: Leaflets can be irregularly lobed or toothed.
- Growth habit: Shrub or treelet structure with upright woody stems.
- Conditions: Bright filtered light, warmth, drainage and even moisture.
- Structure: Some forms can develop irregularly decompound leaves.
Leaf shape in Polyscias guilfoylei 'Roble'
Polyscias guilfoylei can form a shrub or treelet up to about 5 m in tropical conditions. The leaves are usually 1-pinnate, and some forms can become irregularly decompound, creating a layered, divided structure.
Indoors, Polyscias guilfoylei 'Roble' behaves as a warm woody foliage plant. A stable root zone matters because sudden changes in moisture, temperature or light can lead to leaf drop.
Care for Polyscias guilfoylei 'Roble'
- Light: Bright filtered light keeps the woody stems stronger and the foliage denser.
- Watering: Water after the upper layer has dried slightly, then empty excess water from the cover pot.
- Humidity: Moderate to higher humidity reduces dry edges on the leathery leaflets.
- Temperature: Keep warm and protect from cold draughts or sudden temperature drops.
- Substrate: Use an airy, well-drained mix so the roots receive moisture and oxygen together.
- Pruning: Trim selectively above a node to keep the woody outline balanced.
- Repotting: Move up only one pot size when the roots have filled the container.
Troubleshooting Polyscias guilfoylei 'Roble'
- Leaf drop: Relocation, cold or irregular watering can cause sudden shedding.
- Root rot: Heavy wet soil can damage roots and lead to yellowing leaves.
- Dry margins: Drought stress or very dry air can brown leaflet edges.
- Pests: Spider mites, mealybugs and scale can settle along stems and leaflet joints.
- Leaf scorch: Harsh direct sun can mark the glossy leaflets.
Safety for Polyscias guilfoylei 'Roble'
