|---|---|
| CO₂ | Likes humidity above normal room levels (no figure in sources) |
| 水温 | 10°C – 35°C |
| 造景位置 | SUITS closed and open terrariums – among the best terrarium carnivores because it needs no winter dormancy. In a closed tank give strong light and a little ventilation to limit mould. Note: temperate sundews (e.g. D. rotundifolia, D. filiformis, some D. binata forms) DO need a cold winter and are poor closed-terrarium plants. |
