Syngonium podophyllum 'Nguengi Laima' aka (Ngern Lai Ma, Silver Holly)

How to care for Syngonium podophyllum 'Nguengi Laima' at home

Provide medium to bright indirect light, protected from harsh direct sun. Keep temperatures around 18–27 °C and avoid cold below 15 °C. Humidity near 50% is preferable, although lower household humidity is tolerated.

Use an airy, moisture-retentive mix in a pot with drainage holes; equal parts coir, vermiculite and perlite are one option. Water when the root ball has dried slightly, the pot feels lighter and some moisture remains below the surface. Use a wooden stick to check deeper in the mix when needed. Water thoroughly, drain and empty runoff.

Feed lightly about monthly during active growth, following the balanced fertiliser's label. Pause feeding when growth stops and water less often as drying slows. Tie extending stems loosely to a pole. When roots tightly fill the container and it becomes difficult to keep the mix evenly moist, repot the plant in a slightly larger pot with fresh mix.

For propagation during active growth, cut a healthy leafy stem just below a node with a disinfected blade. Remove the lower leaves and insert the node into damp, freely draining rooting mix in a clean pot. Keep the cutting around 18–24 °C in bright indirect light. A clear cover can retain humidity. Keep it off the leaves and open it regularly to let fresh air in and excess condensation clear. Keep the covered cutting out of direct sun to prevent overheating. Keep the mix damp, never waterlogged. Once roots and new growth develop, remove the cover gradually before planting the cutting in houseplant mix.

Common problems with Syngonium podophyllum 'Nguengi Laima' and how to solve them

• Wilt in wet mix: Empty trapped water, clear blocked drainage and pause watering. Inspect roots if wilting persists. Firm roots can remain intact while the mix dries slightly. Cut soft decay back to healthy tissue with disinfected scissors, disinfecting between cuts and afterwards. Discard rot and affected mix; repot the remaining plant in fresh mix and a clean pot with drainage holes. If decay is extensive or the stem base has rotted, discarding the plant may be necessary.
• Water-soaked spots or sticky ooze: Spreading wet-looking lesions, sometimes with yellow halos, can indicate bacterial disease; fungal spots may look similar. Isolate the plant and keep its leaves dry. Keep water draining from the pot away from nearby plants. Improve airflow, remove affected leaves with disinfected tools, bag the waste and disinfect tools between cuts and afterwards. If the spots spread or stems begin to soften, have the plant checked promptly by a plant specialist.
• Stippling with fine webbing: Check undersides for moving mites before treating. Separate an infested plant, inspect neighbours and rinse all leaf surfaces weekly while mites remain.Persistent mites may need insecticidal soap labelled for spider mites on indoor ornamental plants and suitable for Syngonium. Soap must contact the mites to work. Follow the label's repeat timing and precautions; never treat a drought-stressed plant.Test a small area of foliage and check it for damage over at least 48 hours. Follow any longer test period on the label; treat the rest only if no injury appears and the label permits use. Keep the plant separate until repeated checks show that mites have stopped returning.

Syngonium podophyllum ‘Nguengi Laima’ 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.

Syngonium podophyllum: name and meaning

The name Syngonium comes from Greek words meaning “together” and “reproductive organs”, referring to the united ovaries in its flowers. The species name podophyllum means “foot-leaved”, a reference to the foot-like arrangement of mature leaf divisions.

Heinrich Wilhelm Schott established the genus Syngonium in 1829 in Wiener Zeitschrift für Kunst, Literatur, Theater und Mode, volume 3, page 780.

Heinrich Wilhelm Schott first described Syngonium podophyllum in 1851 in Botanische Zeitung (Berlin), volume 9, page 85.
