This page covers what makes 'Siam Aurora' aglaonema different. For light, water, soil, pests, and the rest, read the Chinese evergreen care guide.
What it is
‘Siam Aurora’ is a red Chinese evergreen. Its green leaves have bright pink-red edges and a pink-red stripe down the midrib, with yellow-green blotches between. It is one of the Costa Farms Trending Tropicals, per Select-A-Plant, and one of the most common red aglaonemas. It grows 60 to 90 cm (2 to 3 ft) tall.
How to tell it apart
| Plant | Leaves | The tell |
|---|---|---|
| ‘Siam Aurora’ | Green with red edges and red midrib | Red outlines and a red center line |
| ‘Pink Dalmatian’ aglaonema | Dark green with pink spots | Pink speckles, not outlines |
| ‘Lady Valentine’ | Pink with green edges | Pink covers most of the leaf |
Care differences
The red needs more light than the silver Chinese evergreens. Medium to bright indirect light keeps the edges bright. In low light, the red fades and the plant stops growing.
Red aglaonemas also like warmth. Keep it above 15°C (60°F).
Grow it by division
Divide the clump in spring. Each piece needs stems and roots.
Buying it
‘Siam Aurora’ is common at garden centers and big box stores. Look for bright red edges. Faded red means it sat in low light.
