Aglaonema rotundum

Aglaonema rotundum is a compact Sumatran Aglaonema species with broad, almost round leaves. The upper surface is dark and glossy, crossed by pale to pinkish midribs and veins, while the lower leaf surface develops deep red tones.

The plant grows from a decumbent stem with short petioles and a small upright growing tip, so it sits low and broad in the pot. Warmth, filtered light and careful moisture around the stem base protect the broad leaf surfaces and lower stem.

Aglaonema rotundum with rounded dark leaves

• Rounded-leaf species: A Sumatran Araceae species known for broad leaves and coloured venation.
• Leaf shape: Broad ovate to nearly round leaves give the plant its low, broad outline.
• Upper surface: Dark glossy green leaves show pale to pinkish midribs and veins.
• Underside colour: The lower leaf surface develops dark red tones that are visible when leaves lift or angle.
• Growth habit: A decumbent stem and short petioles keep the plant close to the pot surface.
• Origin: The species comes from wet tropical conditions in North Sumatra.

Red undersides on Aglaonema rotundum

Aglaonema rotundum forms broad, rounded leaf blades with pale to pinkish vein patterning through the dark upper surface. The red underside adds colour when the leaves lift, angle outward or are viewed from below.

The stem naturally rests close to the substrate before rising into a short growing tip. Keep that stem area at the substrate surface during potting so the base stays firm and air can move around it.

Care for Aglaonema rotundum

• Light: Bright filtered light protects the glossy leaves from direct-sun marks while keeping new growth compact.
• Water: Water once the upper substrate begins to dry, then let all excess water drain from the pot.
• Substrate: Use a loose, moisture-retentive mix with bark, coir and mineral drainage around the stem base.
• Temperature: Keep the plant warm; cold wet substrate can damage roots and soften the lower stem.
• Humidity: Moderate to higher humidity helps broad new leaves expand without dry edges.
• Feeding: Feed lightly during active growth, using a diluted fertiliser to avoid salt marks on roots and leaf edges.
• Potting: Keep the decumbent stem close to the surface instead of burying it deeply in substrate.

Common issues with Aglaonema rotundum

• Brown patches: Direct sun can mark glossy leaves and damage pale or pinkish vein areas.
• Soft stem base: Check for wet roots or a buried stem if the plant becomes loose in the pot.
• Dry edges: Moisture swings, dry air or root stress can cause browning along the rounded leaf margins.
• Pests: Inspect the red leaf undersides and short petiole bases for mealybugs, scale and mites.
• Yellow leaves: Cold damp substrate or slow-draining potting mix often shows first in the lower leaves.

Safety information for Aglaonema rotundum

Aglaonema rotundum contains calcium oxalate crystals that can irritate the mouth and digestive tract if chewed. Keep it away from pets and children who may bite leaves or stems.

Botanical background of Aglaonema rotundum

Aglaonema rotundum was published by N.E. Brown in 1893 in Gardeners’ Chronicle. The species epithet rotundum means round, referring to the broad, rounded leaf shape, while the genus name Aglaonema refers to bright, thread-like floral parts.

Aglaonema rotundum keeps a low profile in the pot, with rounded dark leaves, pale to pinkish veins and red undersides.
