Aglaonema pictum tricolor

Aglaonema pictum 'Tricolor'

Aglaonema pictum 'Tricolor' is a patterned form of Aglaonema pictum, a species from Sumatra including Nias. It grows as a low, slow subshrub with short stems and oval leaves marked in several green tones.

The plant forms a compact crown and adds new leaves slowly. New leaves emerge rolled and pale, then firm up as the green mottling becomes clearer.

Key traits of Aglaonema pictum 'Tricolor'

• Selected Aglaonema pictum form with three-tone green leaves
• Oval leaves with dark green, mid-green and pale green mottling
• Compact subshrub habit with slow indoor growth
• Species background from wet tropical Sumatra, including Nias
• Best where warmth, humidity and moisture stay consistent; cold or dry windowsills can stall new leaves and crisp the edges

Leaf pattern and habitat

Aglaonema pictum is an Araceae species from wet tropical forest conditions. In cultivation, 'Tricolor' describes selected plants with three-tone leaf patterning within Aglaonema pictum.

Give it filtered light, warm roots and lightly moist substrate; sudden dry heat or cold air can mark new leaves. In a pot, older stems may slowly lengthen and root from nodes when they sit close to moist substrate.

Care requirements for Aglaonema pictum 'Tricolor'

• Light: Place in bright filtered light, such as an east-facing window or moderate grow-light position.
• Watering: Keep the substrate lightly and evenly moist. Water when the upper 2–3 cm begins to dry.
• Substrate: Use a fine, airy mix with coco coir, small bark, perlite, pumice and a little fine composted leaf matter.
• Drainage: Keep the mix open enough that water drains freely while the roots stay slightly moist.
• Temperature: Keep at 20–28 °C for active growth. Growth slows strongly in cool rooms.
• Humidity: Aim for moderate to high humidity, especially during new leaf expansion. A plant cabinet or humidifier can keep conditions steadier.
• Feeding: Feed very lightly during active growth. Slow-growing pictum forms handle weak, regular nutrition better than heavy doses.
• Repotting: Repot carefully only when roots fill the pot or the substrate has degraded. Disturbed roots recover more cleanly in warm conditions.
• Placement: Choose a stable position away from cold windows, hot radiators and sudden air movement, as new leaves mark more easily when conditions change suddenly.
• Propagation: Propagate by rooted divisions or stem sections with nodes, kept warm and humid while new roots form.

Growth responses

• Yellowing with soft leaf stalks: Check the lower root ball for saturation and improve drainage before watering again.
• Crisp leaf edges: Review humidity, watering consistency and dry heat from radiators or vents.
• Small, weak new leaves: Check temperature and light level; cool conditions slow this species noticeably.
• Leaf marks after shipping or moving: Keep the plant warm and in filtered light until the next leaves harden without new marks.
• Stem stretch with fewer leaves: Check whether the plant is reaching for light and rotate it gradually toward a brighter filtered position.

Slow compact growth

This plant naturally grows slowly and stays compact. Warm roots and stable humidity help new leaves unfurl without sticking or drying at the edges.

Safety and handling

Aglaonema pictum 'Tricolor' contains irritating calcium oxalate crystals. The leaves and stems can irritate the mouth and throat if eaten, so place the plant where pets and children cannot reach it. Wash hands after cutting or dividing stems.

Aglaonema pictum etymology

The botanical name is Aglaonema pictum (Roxb.) Kunth, in the Araceae family. Aglaonema is commonly derived from Greek roots meaning bright or shining and thread. The species epithet pictum comes from Latin pictus, meaning painted or coloured, referring to marked foliage. In horticultural use, 'Tricolor' describes selected plants with three green tones on the leaves.

Aglaonema pictum 'Tricolor' needs steadier warmth, humidity and moisture than most common Chinese evergreen cultivars.
