How it differs
- Much smaller flowers than a typical moth orchid hybrid.
- Sequential blooming on green spikes instead of single flush only.
- Frequent keiki production on old nodes.
- Compact plant suitable for limited space.
Strengths
- Extended display when spikes are left intact.
- Good choice for miniature and windowsill collections.
- Adaptable under indoor light when kept warm and humid.
Care in one minute
Provide bright, indirect light such as an east window or shaded south exposure.
Use a coarse bark mix with excellent drainage; repot after flowering when media breaks down.
Water when the mix is nearly dry; soak and drain; avoid standing water in the crown.
Keep 65 to 85 °F (18 to 29 °C) and 40 to 60 percent humidity; add airflow.
Fertilize lightly during growth; flush occasionally to remove salts.
Leave healthy green spikes in place to allow sequential blooms.
Watch‑outs
- Old spikes can look untidy if many keikis form.
- Underwatering or stale mix leads to wrinkled leaves.
- Bud drop with abrupt temperature swings.

Provenance note
