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 with short, steady growth. New leaves emerge rolled, harden gradually and show stronger pattern definition as the blade matures, so the plant develops its best appearance through steady, warm growth.

Aglaonema pictum 'Tricolor' key traits

• Horticultural tricolour form of Aglaonema pictum
• 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
• Well suited to warm rooms, vitrines or plant cabinets

Aglaonema pictum 'Tricolor' leaf pattern and habitat

Aglaonema pictum is an Araceae species that grows primarily in wet tropical biome conditions. In cultivation, 'Tricolor' describes selected plants with three-tone leaf patterning within Aglaonema pictum.

The habitat background explains the cultivation needs clearly: filtered light, warm roots, consistent moisture and stable air around the leaves. In a pot, older stems may slowly lengthen and root from nodes when they sit close to moist substrate.

Aglaonema pictum 'Tricolor' care requirements

• 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 forest-floor style mix with coco coir, small bark, perlite, pumice and a little leaf-mould-style organic matter.
• Drainage: Keep the mix open enough that water drains freely while the root zone stays 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 vitrine, cabinet or humidifier can help maintain stable conditions.
• Feeding: Feed very lightly during active growth. Slow-growing pictum forms respond better to weak, regular nutrition than heavy doses.
• Repotting: Repot carefully only when roots fill the pot or the substrate has degraded. Disturbed roots recover best in warm conditions.
• Placement: Keep away from cold windows, hot radiators and sudden air movement, as leaf expansion is sensitive to unstable conditions.
• Propagation: Propagate by rooted divisions or stem sections with nodes, kept warm and humid while new roots form.

Aglaonema pictum 'Tricolor' growth responses

• Yellowing with soft petioles: Check the lower root ball for saturation and improve drainage before watering again.
• Crisp leaf edges: Check humidity, watering consistency and warm airflow 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 stable while new growth develops under consistent light.
• Stem stretch with fewer leaves: Check whether the plant is reaching for light and rotate it gradually toward a brighter filtered position.

Aglaonema pictum 'Tricolor' slow-growth note

This plant has a naturally slow, compact growth pace. A steady root zone, warm room temperature and stable humidity support clean foliage and gradual crown development.

Aglaonema pictum 'Tricolor' safety

Aglaonema pictum 'Tricolor' contains insoluble calcium oxalate crystals. The leaves and stems can irritate the mouth and throat if chewed, so keep the plant away from pets and children. Wash hands after cutting or dividing stems.

Aglaonema pictum 'Tricolor' name origin

The botanical name is Aglaonema pictum (Roxb.) Kunth, in the Araceae family. Aglaonema is commonly derived from Greek roots meaning bright or clear 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' is for collectors who enjoy compact growth, warm stable care and detailed three-tone green patterning.
