Aglaonema 'Red Zircon'

Botanical background of Red Zircon

Red Zircon is a named Aglaonema grown for compact leaves patterned in blush, salmon pink and deep green. It is part of the modern group of colourful Chinese evergreen cultivars and keeps the genus’s clumping, cane-based growth.

Aglaonema belongs to the aroid family and comes from tropical and subtropical Asia. Across the genus, evergreen shoots occupy warm forest understories and renew from the base as older leaves age. Red Zircon carries this growth habit in a compact plant with unusually pink foliage.

Care for aroid canes, roots and new growth

• Propagation: A rooted basal division is the simplest method. Healthy cane pieces with at least one node can also root in warm, lightly moist substrate.
• Light: Medium to bright indirect light suits Aglaonema ‘Red Zircon’, with the brighter end supporting compact growth and clearer colour. Shield the foliage from abrupt direct sun.
• Temperature and humidity: Maintain steady indoor warmth and avoid prolonged chilling conditions, especially while the root ball is moist. Moderate indoor humidity is usually sufficient when the plant is kept away from cold draughts and hot radiators.
• Substrate and repotting: Use an open, moisture-buffered mix containing coir or peat, fine bark and perlite or pumice. Let the plant acclimatise before moving it up by only one pot size.
• Feeding: Use a complete houseplant feed at low strength during active growth. Avoid overfeeding, reduce the frequency when growth slows and do not apply fertiliser to dry soil.

Troubleshooting Aglaonema 'Red Zircon'

• Several leaves yellowing: Check moisture below the surface. A container that stays heavy for a long time can indicate persistent wetness; examine the root system if yellowing continues or the stems begin to loosen.
• Brown edges: Fertiliser residue, repeated dryness, hot airflow and low humidity are common contributors. Correct the strongest cause, rinse the potting mix with plain water and trim only fully dead tissue.
• Soft or dark stem: Chilling or prolonged wetness can damage the short cane. Keep the plant warm, stop watering until the root zone is assessed and remove decay back to firm tissue.
• Pale dry patch: A mark on the side facing the glass usually points to sun scorch. Relocate the pot to bright filtered light and acclimatise slowly to any stronger position.
• Pink colour varies: Blush, salmon and green proportions naturally differ from leaf to leaf. Judge plant health by firm new growth, not by expecting every blade to match.
• Pests in tight joints: Look where each leaf meets the stem for mealybugs, aphids, mites or immobile scale. Isolate the pot, remove visible insects and continue a suitable control until no new activity appears.

Aglaonema ‘Red Zircon’ 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.

What does Aglaonema mean, and who first published it?

Aglaonema combines Greek aglaos, meaning shining or splendid, with nema, meaning thread or filament.
