Aglaonema is a genus of flowering plants in the arum family, Araceae. They are native to tropical and subtropical regions of Asia and New Guinea. They are known commonly as Chinese evergreens.
‘Red Valentine’ grows in a bushy, upright manner. The leaves emerge from the center of the plant and arch outwards as they mature. The leaves are broadly lanceolate to ovate, meaning they are shaped somewhat like a lance or an egg, with a pointed tip. They are relatively large, often growing to lengths that can exceed 10 inches under good conditions.
Its variegated leaves are the most unique feature of this plant among aglaonemas. The variegation, consists of bright red to pink splotches, streaks, or spots scattered across the leaves. This variegation can appear almost as if the leaves have been painted with red watercolor, with the intensity and pattern varying from leaf to leaf.
This plant can grow to be quite large, potentially reaching heights of 2 to 3 feet (60-90 cm) and spreading about the same width when given optimal conditions. Like other Aglaonemas, it’s effective at removing toxins from the air, contributing to a healthier indoor environment.
Care Requirements
- Light: While Aglaonemas in general can tolerate lower light, ‘Red Valentine’ benefits from bright, indirect light to maintain its vibrant coloration. Direct sunlight should be avoided as it can scorch the leaves, but too little light might lead to less variegation.
- Watering: Like other Aglaonemas, ‘Red Valentine’ prefers to dry out slightly between waterings. Overwatering can lead to root rot, so it’s important to check the soil before watering. Water when the top inch or so of soil feels dry.
- Humidity: This variety appreciates higher humidity levels. Humidity trays, regular misting, or a humidifier can help maintain the ideal environment. Low humidity might cause leaf tips to brown.
- Temperature: It thrives in warm environments, ideally between 60-80°F (15-27°C). It’s sensitive to cold drafts, so keep it away from windows or doors during colder months.
- Soil: A well-draining potting mix is crucial. Adding perlite or orchid bark to regular potting soil can improve drainage and prevent waterlogging.
- Fertilization: Feed with a balanced, water-soluble fertilizer during the growing season (spring and summer). Reduce or halt fertilization in fall and winter.
Special Considerations
- Toxicity: Like all Aglaonemas, ‘Red Valentine’ is toxic to pets if ingested, so it should be kept out of reach of cats and dogs.
- Pests: While generally hardy, it can be susceptible to common houseplant pests like spider mites, mealybugs, and scale, especially in dry conditions. Regular inspection and maintaining humidity can help prevent infestations.
- Propagation: Can be propagated through stem cuttings or division. Stem cuttings should include a node and can be rooted in water or directly in soil.
