About Aglaonema
The most colorful plant that thrives in the darkest corners — aglaonema has revolutionized Filipino...
Aglaonema — commonly called Chinese evergreen, or simply "agla" among Filipino plant collectors — has undergone a remarkable transformation from a modest green foliage plant to one of the most vibrant and sought-after ornamental plants in Southeast Asian horticulture. While traditional aglaonema species feature elegant but subdued silver-green patterns, modern Thai and Indonesian hybrid programs have produced varieties with leaves in stunning shades of red, pink, salmon, orange, and multicolor combinations that would not look out of place in a tropical flower garden. The difference between a classic green 'Silver Bay' and a modern 'Super Red' is so dramatic they barely appear to be the same genus.
The genus Aglaonema belongs to the Araceae family (the aroid family, alongside philodendron, monstera, and peace lily) and comprises approximately 20-25 species native to the tropical forests of Southeast Asia — including the Philippines, where several species grow wild in the forest understory. This native Southeast Asian origin is the key to aglaonema's exceptional performance in Filipino homes: the plant evolved in precisely the conditions that Filipino indoor spaces provide — warm, humid, and shaded. While many popular houseplants come from distant origins and merely tolerate indoor conditions, aglaonema genuinely thrives in them.
Aglaonema species have been cultivated as ornamental foliage plants in China and Southeast Asia for centuries — the Chinese name translates to "evergreen through ten thousand years," reflecting its longevity and cultural associations with good fortune and prosperity.
How to Plant Aglaonema in the Philippines
Soil, spacing, and the best planting approach for Philippine conditions.
Aglaonema is among the most widely available ornamental plants in the Philippines. Common varieties cost ₱100-300 at garden centers, plant shops, weekend tiangge, and online sellers. Premium colored varieties run ₱300-1,000+. Rare collector varieties can reach ₱1,000-5,000+. Facebook plant groups and Shopee/Lazada offer the widest variety selection.
Care Guide
Keep your Aglaonema healthy and thriving.
Low to medium indirect light — aglaonema's signature strength. Green varieties survive in remarkably dim conditions (fluorescent office light, windowless bathrooms with artificial light).
Moderate — water when the top 2-3 cm of soil is dry. Aglaonema stores some moisture in its thick, fleshy stems and prefers slight drying between waterings rather than constant wetness.
Light, well-draining, aroid-friendly mix. Coco peat + perlite + compost (2:1:1) is ideal. Add chopped coconut husk or orchid bark for extra drainage.
Aglaonema tolerates a wider humidity range than many aroids — 40-80% is acceptable, though 60-80% (natural Philippine conditions) is optimal.
Moderate feeder. Apply diluted liquid fertilizer (half-strength 10-10-10) monthly during the growing season (wet season). Organic fish emulsion is excellent. Reduce to every 2-3 months during the dry/cool season.
Minimal — remove yellowed or damaged leaves by cutting at the base with clean scissors. If the plant becomes leggy with age (bare stem, leaves only at top), rejuvenate by cutting the stem back to 10-15 cm.

Aroid Potting Mix
BestCoco peat + perlite + compost (2:1:1) in a pot with drainage holes provides the ideal balance of moisture retention and drainage. Add chopped coconut husk or bark for extra aeration. Light, well-draining, and slightly acidic — the perfect environment for aglaonema roots. Repot every 1-2 years in fresh mix.
Water (Passive Hydroculture)
GoodAglaonema adapts well to water culture — place clean stem cuttings or established plants (with roots rinsed free of soil) in water-filled glass containers. Change water weekly to prevent stagnation. Add liquid fertilizer at quarter-strength. Popular as a decorative display method — the clean, soil-free aesthetic suits modern Filipino interiors. Growth is slower than in soil but the plant survives indefinitely.
LECA (Semi-Hydroponics)
GoodLECA (lightweight expanded clay aggregate) in cache pots with water reservoir provides excellent root aeration with consistent moisture. Popular among Philippine plant collectors for premium varieties — reduces root rot risk compared to soil. Requires nutrient solution supplementation since LECA provides no nutrition. Transfer from soil to LECA requires a transition period for root adaptation.
Ornamental Uses
How to use Aglaonema in your garden and home.
Aglaonema's ornamental versatility is unmatched among shade plants — no other genus offers both low-light tolerance AND such dramatic leaf coloration. This dual quality makes it the go-to plant for adding living color to dim indoor environments where flowering plants and colorful foliage plants typically fail.
- Desktop and tabletop accent: Compact aglaonema varieties in decorative pots bring color to desks, coffee tables, dining tables, and shelves. The bold leaf patterns create visual interest at eye level without overwhelming the space. Perfect for offices and study areas
- Floor plant for dim corners: Larger specimens fill empty dim corners with lush, colorful foliage — transforming dead spaces into living features. Place on decorative stands to elevate the display. Groups of 3-5 aglaonema in varying sizes create layered, garden-like indoor compositions
- Office and commercial interior: The classic office plant — aglaonema in hotel lobbies, restaurant interiors, mall atriums, and corporate offices provides maintenance-friendly greenery that survives artificial lighting, air conditioning, and intermittent care
- Bathroom display: The humidity of bathrooms creates ideal conditions. Place on vanities, windowsills, or shelving for lush greenery that thrives where most plants struggle
- Shade garden ground cover: Mass plantings of aglaonema under trees create colorful ground-level displays in areas too shaded for flowering plants. Red and pink varieties are particularly striking as landscape plants
- Border and edging in shade: Rows of a single variety create clean, colorful borders along shaded walkways, under building overhangs, and around garden features in filtered light
- Container groupings on shaded patios: Collections of different varieties in matching pots create display gardens on covered terraces and lanais — a low-maintenance, high-impact approach to Filipino outdoor living spaces
Safety & Environmental Benefits
Toxicity info and air quality benefits.
Humans: Aglaonema contains calcium oxalate crystals (raphides) in all parts — leaves, stems, and roots. Chewing or ingesting plant material causes immediate intense oral irritation, burning pain, swelling of the mouth and throat, drooling, and potential difficulty swallowing. The pain typically prevents significant ingestion. Skin contact with sap may cause mild irritation in sensitive individuals. Handle with care during pruning and propagation — wash hands after handling.
Aglaonema was tested in the NASA Clean Air Study (1989) and demonstrated effectiveness at removing indoor air pollutants, specifically formaldehyde and benzene — common volatile organic compounds (VOCs) off-gassed by furniture, carpeting, paint, cleaning products, and building materials.
Common Pests & Diseases
Spot issues early and keep your plant healthy.
Mealybugs
White, cottony clusters at leaf axils (where leaves meet stems) and on undersides — the most common aglaonema pest. Suck sap and excrete honeydew that promotes sooty mold. Treat with neem oil, alcohol-dipped cotton swabs, or insecticidal soap. Regular leaf wiping during inspections catches infestations early.
Scale insects
Brown bumps on stems and leaf midribs that suck sap. Cause yellowing and weak growth. Remove with alcohol-soaked cotton. Apply horticultural oil for heavy infestations. More common on stressed or overcrowded plants.
Spider mites
Tiny mites causing stippled yellowing and fine webbing, especially in dry indoor conditions. Increase humidity, mist fronds, wipe with damp cloth. Neem oil or miticide for severe infestations. More problematic in air-conditioned rooms with low humidity.
Root rot (Pythium, Phytophthora)
The most serious disease — caused by overwatering and poor drainage. Symptoms: yellowing leaves, mushy stems, foul soil odor. Prevention: well-draining mix, drainage holes, allow soil to dry partially between waterings. For infected plants: unpot, trim rotted roots, repot in fresh mix, reduce watering.
Bacterial leaf spot (Xanthomonas)
Water-soaked spots on leaves that enlarge and turn dark brown with yellow halos. Spreads through water splash and contaminated tools. Remove affected leaves. Avoid overhead watering. Ensure air circulation. Copper-based bactericide for severe cases.
Anthracnose
Tan-brown leaf spots with dark margins — fungal disease favored by warm, wet conditions. Remove affected leaves, improve air circulation, avoid wetting foliage. Fungicide spray for persistent problems.
Frequently Asked Questions
Quick answers about Aglaonema.
Is aglaonema good for low light?
One of the BEST low-light plants. Green/silver varieties tolerate remarkably dim conditions (fluorescent-only offices, windowless rooms). Colorful red/pink varieties need brighter indirect light to keep vivid colors — they revert to green in deep shade. Rule: greener = lower light OK; more colorful = more light needed. No direct sun for any variety.
Is aglaonema toxic to pets?
Yes — ASPCA lists it as toxic to dogs and cats. Contains calcium oxalate crystals that cause oral pain, drooling, swelling when chewed. Usually self-limiting (pain stops chewing). Severe cases: veterinary attention. Place on high shelves or in pet-free rooms. Choose pet-safe alternatives (spider plant, calathea) for accessible spots.
What are the most popular aglaonema varieties in the Philippines?
Top picks: 'Siam Aurora' (red edges), 'Lady Valentine' (pink center), 'Pink Dalmatian' (pink spots), 'Red Valentine' (deep red), 'Silver Bay' (classic silver-green, best low-light), 'Maria' (dark green, ultra shade-tolerant), 'Super Red' (intensely red). Common varieties ₱100-300, premium ₱300-1,000+.
Why are my aglaonema leaves turning yellow?
Most likely overwatering (#1 killer). Check: lower leaves yellowing = reduce watering, ensure drainage. Multiple yellow = possible root rot (inspect roots). Edge browning = too much light or fertilizer burn. Single old leaf yellowing = natural aging (normal). Leaf curling = cold damage from AC drafts.
Can aglaonema grow outdoors in the Philippines?
Yes — thrives outdoors in SHADE. Native to Southeast Asian forest understory. Best spots: under trees, shaded patios, beneath overhangs. NEVER direct sun. Outdoor aglaonema often grows larger and more vigorously than indoor due to higher humidity and better light. Excellent as shade garden ground cover or border plant.
How do you propagate aglaonema?
Division (easiest): separate multiple stems when repotting. Stem cuttings: 10-15 cm with 2+ nodes, plant in moist mix or root in water. Water propagation: cuttings in water, roots in 2-4 weeks. All methods 80-90%+ success rate. One mature plant yields 3-5 new plants through division.
Does aglaonema purify air?
Yes — NASA Clean Air Study confirmed aglaonema removes formaldehyde and benzene from indoor air. Especially valuable because it FUNCTIONS in low light where many air-purifying plants don't photosynthesize effectively. Multiple plants improve air quality in new condos, offices, and recently renovated spaces.
How long does aglaonema live?
10-20+ years with basic care. Many Filipino families have multigenerational aglaonema inherited from parents/grandparents. When leggy: cut back to 10-15 cm, new growth in 2-4 weeks, root the cut top as new plant. Periodic division and rejuvenation means the plant essentially renews itself indefinitely.
