Aglaonema pictum 'Tricolor', often called the Tricolor Chinese Evergreen or sometimes just Tricolor Aglaonema, is a striking and popular houseplant prized for its uniquely patterned leaves. This cultivar of Aglaonema pictum features elongated, lance-shaped leaves with a captivating combination of green, white, and pink or reddish variegation, creating a vibrant and eye-catching display. It belongs to the Araceae family.
The genus name Aglaonema comes from the Greek words aglaos (bright, shining) and nema (thread), possibly referring to the shiny stamens of some species. Pictum means "painted" or "coloured," reflecting the plant's variegated foliage. 'Tricolor' clearly describes the three distinct colours present on the leaves.
Light: Aglaonema pictum 'Tricolor' prefers bright, indirect light. Direct sunlight can scorch the leaves and fade the vibrant colours, while insufficient light can lead to less pronounced variegation and slower growth. A spot near a window with filtered light, or a room with ample ambient light, is ideal.
Water: Allow the top inch or two of soil to dry out slightly between waterings. Water thoroughly when you do water, ensuring any excess drains away. Overwatering can lead to root rot, while allowing the plant to dry out too much can cause the leaves to wilt and brown.
Potting mix: A well-draining potting mix is essential. A standard houseplant potting mix, amended with perlite or orchid bark to improve drainage, is a good choice. Avoid mixes that retain too much moisture.
Fertilising: Feed your Aglaonema pictum 'Tricolor' with a diluted balanced liquid fertiliser every 4-6 weeks during the growing season (spring and summer). Reduce or stop fertilising during the autumn and winter months.
Temperature: Aglaonema pictum 'Tricolor' prefers typical room temperatures, roughly between 18-24°C (65-75°F). It is not frost-tolerant and should be protected from cold temperatures. Avoid placing it near draughts or heating/cooling vents.
Humidity: While Aglaonema pictum 'Tricolor' can tolerate average household humidity, it appreciates slightly higher levels. Regularly misting the leaves or placing the plant on a pebble tray filled with water can be beneficial, especially in drier environments.
Variegation: The distinctive tricolour variegation is a key characteristic of this cultivar. The patterns and proportions of green, white, and pink/red can vary, making each plant unique.
Toxicity: Like other Aglaonemas, 'Tricolor' is toxic if ingested, so it's best to keep it away from pets and small children.
