Aglaonema Siam Aurora
📖 About this plant
Aglaonema Siam Aurora (also known as Red Valentine or Siam) is a stunning variety celebrated for its bold, dramatic coloration. The lance-shaped dark green leaves are framed by brilliant red-pink margins and feature equally vibrant red midribs and petioles. The color intensifies in brighter light, creating a striking display that adds a warm, tropical feel to any space. Siam Aurora is a relatively compact grower, making it perfect for desks, tabletops, and small apartments. The fiery red and green combination makes it one of the most photogenic Chinese Evergreen varieties available.

Common issues

💡 Care tips
- Bright indirect light brings out the most vivid red and pink coloration — in low light, leaves may revert to mostly green. Avoid direct sunlight which can scorch the colorful portions. The red stems and petioles are a beautiful ornamental feature even before leaves fully develop. Use filtered water to prevent tip burn. This variety is more compact than Silver Bay, making it ideal for smaller spaces.
