Aglaonema 'Diamond Bay'

Aglaonema 'Diamond Bay' is a silver-green Chinese evergreen with broad, lance-shaped leaves and a full clumping habit. The leaf blade has a wide grey-green centre, deeper green margins and a smooth surface, creating a calm, evenly patterned crown.

New growth rises from short basal shoots, gradually making the plant denser from the base as it matures. In indoor containers it stays compact, leafy and upright, with long petioles holding the foliage slightly above the pot.

Aglaonema 'Diamond Bay' silver-leaf traits

• Broad silver-grey leaf centres framed by green margins
• Lance-shaped leaves with a smooth, gently arching surface
• Clumping basal growth that creates a full indoor plant
• Cultivated selection from the Aglaonema 'Silver Bay' line
• Steady foliage plant for warm rooms with filtered light

Silver centres and cultivar background

Aglaonema 'Diamond Bay' was selected from tissue-cultured Aglaonema 'Silver Bay' material. Its foliage differs through a broad central silver-green zone and a simpler edge pattern, with darker green margins framing each leaf.

The plant grows as a short-stemmed evergreen clump. Older leaves sit around the outside of the crown while new leaves emerge from the centre and from side shoots near the base. This growth pattern helps mature plants keep a rounded outline in pots.

Aglaonema 'Diamond Bay' indoor care

• Light: Give medium to bright filtered light. The pale centre marks easily in hot direct sun, especially close to glass.
• Watering: Water when the upper 2–4 cm of substrate feel dry. Keep the root ball evenly moist during active growth, then let it partially dry again.
• Substrate: Use a loose mix with coco coir, fine bark and perlite. The roots need moisture retention with enough air around the lower stems.
• Drainage: Use a pot with drainage holes and empty any standing water from the cover pot after watering.
• Temperature: Keep at 18–27 °C where possible. Protect the plant from cold windowsills, draughts and temperatures below 16 °C.
• Humidity: Average indoor humidity is usually enough. Very dry heated rooms can increase brown tipping and pest pressure.
• Feeding: Feed lightly in spring and summer, about once a month at reduced strength. Rinse the substrate occasionally to prevent salt build-up.
• Repotting: Repot when the root ball is firm or watering runs straight through. Move up by one modest pot size.
• Grooming: Cut ageing leaves at the base. Spathes can be removed early to keep the crown dense with foliage.
• Propagation: Divide rooted basal shoots during repotting, keeping leaves and roots on each division.

Cold, light and root checks

• Grey, water-soaked patches: Cold injury is likely. Check for chilly glass, winter transport stress or draught exposure.
• Yellow lower leaves: Check the lower root ball for wetness, dryness or compacted substrate before changing the watering pattern.
• Brown tips: Usually linked to dry intervals, fertiliser salts or very dry air. Flush the mix gently and reduce feed strength.
• Bleached pale areas: Move the plant back from direct sun or heat concentrated through window glass.

Sap safety and toxicity

Aglaonema 'Diamond Bay' contains insoluble calcium oxalate crystals. Keep it away from pets and small children. Chewed leaves or stems can irritate the mouth, lips, tongue and throat, and sap may irritate sensitive skin.
