Aglaonema 'Red Valentine'

Aglaonema 'Red Valentine'

Aglaonema 'Red Valentine' is a compact Chinese evergreen cultivar with broad glossy leaves, red-pink centres, green margins and defined green veining. New leaves rise from a short central crown, giving young plants a neat layered shape, while mature plants become fuller as basal shoots develop.

The colour spreads across much of the blade, and the green edge gives each leaf a clear outline. In a pot, Aglaonema 'Red Valentine' stays compact and builds density slowly through short stems and basal shoots.

Aglaonema 'Red Valentine' leaf shape and pattern

• Growth habit: Compact clumping crown with short stems and a rounded indoor outline.
• Leaf shape: Broad oval to lance-shaped leaves with a smooth, glossy surface.
• Colour pattern: Red-pink centres, green margins and green venation.
• Pot behaviour: Slow to moderate growth with width added through basal shoots.

Aglaonema 'Red Valentine' indoor growth

Aglaonema are evergreen aroids from warm, sheltered habitats from north-eastern India through tropical Asia to Papua New Guinea. Aglaonema 'Red Valentine' grows indoors with bright filtered light, temperatures above 18 °C without cold draughts and a potting mix that does not stay wet.

The name Aglaonema comes from Greek roots meaning bright or clear and thread, referring to the stamens.

Older stems may become cane-like with age, while younger plants hold most of their foliage close to the crown. Warmth above 18 °C, filtered light and a draining mix reduce brown or translucent patches on the red-pink leaves.

Care essentials for Aglaonema 'Red Valentine'

• Light: Place in bright filtered light. Morning or late-afternoon sun through a sheer curtain is usually suitable.
• Watering: Water when the upper 2–4 cm of substrate feels dry. Keep the substrate lightly moist during active growth.
• Substrate: Use an airy aroid mix with coco coir or fine bark, perlite or pumice, and a small moisture-holding organic fraction.
• Drainage: Let excess water leave the pot fully after watering, especially in decorative cachepots.
• Temperature: Keep above 18 °C and away from cold draughts. This helps new leaves emerge without stalling or curling.
• Humidity: Moderate household humidity is usually enough. Very dry heated air may crisp the finest leaf edges.
• Feeding: Feed lightly every 4–6 weeks during active growth with a diluted complete fertiliser.
• Repotting: Move up one pot size when roots fill the container and watering becomes noticeably more frequent.
• Pruning: Remove ageing lower leaves at the base. Bare older stems can be shortened above a node.
• Propagation: Root stem sections with nodes or divide basal shoots once they have their own roots.

Reading Aglaonema 'Red Valentine' leaves and roots

• Soft yellow leaves: Check for wet substrate, cool roots and poor drainage. Allow the mix to dry slightly before watering again.
• Brown leaf patches: Move the plant out of direct sun, hot glass or cold draughts.
• Loose, stretched growth: Increase filtered light gradually and rotate the pot so the crown does not lean strongly toward the light.
• Crisp tips: Review watering pattern, fertiliser strength and dry indoor heat.

Aglaonema 'Red Valentine' safety

Keep Aglaonema 'Red Valentine' out of reach of pets and children that may eat the foliage. Insoluble calcium oxalate crystals in the plant can irritate the mouth and throat if ingested, and sap contact may irritate sensitive skin.

Red-pink leaves, green margins and green venation stay neat in a compact indoor crown.
