Queen of Siam Aglaonema
🌿 Product Name: Aglaonema 'Queen of Siam'
🔬 Scientific Name: Aglaonema hybrid 'Queen of Siam' (Thai-bred Aglaonema cultivar, part of the commutatum/rotundum hybrid group)
☠️ Medicinal value: Not used medicinally — mildly toxic like other Aglaonema cultivars. Contains calcium oxalate crystals that irritate the mouth and throat if chewed or ingested; no established therapeutic use.
🌎 Origin: A cultivated hybrid developed in Thailand, part of the country's extensive Aglaonema breeding tradition (Thailand is considered the epicenter of ornamental Aglaonema hybridization); parent species trace back to tropical Southeast Asia (Philippines, Indonesia, Malaysia, southern China).
🎨 Uses: Purely ornamental — grown for its richly variegated leaves, typically showing bold pink, red, or crimson patterns against green, considered one of the more premium/showy Aglaonema hybrids. Popular as a decorative indoor houseplant and collector's variety, valued both for aesthetics and reputed air-purifying qualities.
🌡️ Plant needs: Warm indoor temperatures (68–80°F / 20–27°C), moderate to high humidity, and low to medium indirect light — brighter indirect light helps intensify and maintain the pink/red variegation without direct sun exposure. Well-draining, fertile potting soil.
💧 How to care: Water when the top inch of soil feels dry; avoid overwatering, which leads to root rot. Keep out of direct sun to prevent leaf scorch and color fading; too little light causes the variegation to become dull or greener. Fertilize lightly every 4–6 weeks during spring/summer. Wipe leaves periodically to keep them dust-free and glossy. Protect from cold drafts and temperatures below 55°F (13°C).
⚠️ Warning (children & pets): All parts contain calcium oxalate crystals, toxic if chewed or swallowed. Symptoms include mouth and throat irritation, burning, drooling, and swelling; can cause vomiting in cats and dogs. Keep out of reach of young children and pets, and seek medical or veterinary attention immediately if ingestion occurs.
