History / Discovery / Cultivator

Aglaonema ‘Siam Aurora’, often called Red Aglaonema or Chinese Evergreen, is a captivating cultivar celebrated for its vibrant foliage and ease of care. The genus Aglaonema is native to the tropical and subtropical regions of Asia, including countries like Thailand, Indonesia, Malaysia, and the Philippines. These plants thrive in the shaded understories of rainforests, benefiting from the warm, humid conditions and dappled sunlight.

The development of Aglaonema ‘Siam Aurora’ involved careful selection and hybridization by plant breeders. While the precise origins and the identity of the original cultivator remain somewhat obscure, it is widely believed that ‘Siam Aurora’ emerged from Thailand (formerly Siam), lending the cultivar its distinctive name. Thai plant breeders are renowned for their expertise in cultivating ornamental plants, particularly those with striking variegation and unique color patterns.

The popularity of Aglaonema ‘Siam Aurora’ soared due to its exceptional visual appeal. The plant features lance-shaped leaves adorned with a rich, deep green base, dramatically edged and flushed with vibrant shades of red and pink. This striking contrast of colors creates a visually stunning display, making it a sought-after choice for both novice and experienced plant enthusiasts. The bold colors not only add a touch of exotic beauty but also bring warmth and vibrancy to indoor spaces.

Aglaonema, as a genus, has a rich history in cultivation. They were first introduced to the Western world in the 19th century and have since become increasingly popular as houseplants due to their adaptability to indoor conditions and relatively low maintenance requirements. The ‘Siam Aurora’ variety is a testament to the ongoing efforts to create more visually appealing and resilient Aglaonema cultivars.

The cultivation of Aglaonema ‘Siam Aurora’ has significantly contributed to its global availability. Plant nurseries and horticultural centers across the world propagate this cultivar through various methods, including stem cuttings and tissue culture. The ease of propagation, combined with its high demand, has made it widely accessible to plant lovers worldwide.

In summary, Aglaonema ‘Siam Aurora’ is a remarkable cultivar that embodies the beauty and resilience of the Aglaonema genus. Its origin in Thailand, coupled with the dedication of plant breeders, has resulted in a plant that is both visually stunning and relatively easy to care for. Its vibrant red and green foliage makes it a popular choice for adding a splash of color and tropical flair to any indoor environment. Its continued popularity underscores its enduring appeal and its significance in the world of ornamental plants. The story of ‘Siam Aurora’ is a beautiful example of how selective breeding can enhance nature’s already impressive designs.

Plant Care Summary

Botanical Insights

Adaptations

Aglaonema ‘Siam Aurora’ exhibits several adaptations that contribute to its success as a houseplant. Its tolerance of low light conditions is a significant adaptation, allowing it to thrive in indoor environments where sunlight is limited. This is linked to its ability to efficiently photosynthesize even under low light intensity. Furthermore, its relatively thick, waxy leaves help to reduce water loss through transpiration, making it drought-tolerant to some extent. This adaptation is crucial in its native habitat and beneficial in drier indoor environments. The plant also has adaptations to help it grow in the shady understories of forests.

Propagation Methods

Aglaonema ‘Siam Aurora’ can be effectively propagated through several methods. Stem cuttings are a common and reliable method. Cuttings should be taken from healthy stems and rooted in water or directly in a well-draining potting mix. Division is another viable method, especially for mature plants with multiple stems. During repotting, the plant can be carefully divided, ensuring that each division has a portion of the root system. Air layering can also be used, where roots are encouraged to grow on a stem while it is still attached to the parent plant. Once sufficient roots have formed, the layered stem can be separated and planted.

Toxicology

Aglaonema ‘Siam Aurora’ contains calcium oxalate crystals, which are toxic to humans and pets. If ingested, these crystals can cause immediate pain and irritation in the mouth, lips, and tongue. Symptoms may include excessive drooling, difficulty swallowing, and vomiting. While the toxicity is generally considered mild to moderate, it is essential to keep the plant out of reach of children and pets. If ingestion occurs, rinsing the mouth with water and seeking medical or veterinary attention is recommended. For pets, signs like pawing at the mouth, foaming, and loss of appetite warrant immediate veterinary consultation.

Common Problems

Pests:

• Mealybugs
• Spider Mites
• Aphids

Diseases:

• Root Rot (due to overwatering)
• Leaf Spot (fungal or bacterial)

Other:

• Leaf Yellowing: Can be caused by overwatering, underwatering, or nutrient deficiency.
• Browning Tips: Often due to low humidity or fluoride in tap water.
• Slow Growth: Insufficient light or nutrient deficiency.

Rarity & Value

Rarity:

While not exceedingly rare, Aglaonema ‘Siam Aurora’ can be considered somewhat less common than standard green Aglaonema varieties. Its vibrant coloration requires careful cultivation to maintain stability and vibrancy, potentially contributing to its slightly lower availability. Furthermore, high demand from collectors who appreciate the plant’s visual appeal also contributes to its relative rarity.

Value:

The value of Aglaonema ‘Siam Aurora’ specimens is primarily influenced by the intensity and stability of its variegation, the size of the plant, and its overall health and condition. Plants with consistently bright and well-defined red and pink hues are generally more valuable. Larger, more mature specimens command higher prices. The current collector trends and the plant’s provenance (if known) can also play a role in determining its market value. A well cared for, robust plant is always going to be more valuable.
