Moth Orchid Phalaenopsis equestris

Phalaenopsis equestris

Phalaenopsis equestris is a compact, floriferous moth orchid species from the Philippines and southern Taiwan. Plants stay small and produce many pink to rose‑purple flowers on branching spikes. Spikes may flower sequentially for months, and keikis sometimes form on older nodes. This species underpins many miniature and novelty hybrids. It performs well as a houseplant in bright, indirect light with warm temperatures and a bark‑based mix.

  • Fragrance: 0 none
  • USDA hardiness: not hardy outdoors in most areas; greenhouse only in frost‑free zones 10 to 12; grow indoors elsewhere
  • Breeder / Year / Origin: unknown, wild species, S Taiwan to Philippines
  • Cut‑flower notes: slender stems; typical vase life about 8 to 14 days depending on season and source
  • Pet safety: safe

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.

Best uses (tags)

containers, houseplant, shade‑tolerant, beginners, novelty breeding

Provenance note

A Philippine and south Taiwan species widely used in breeding; size and sequential blooming make it a staple in novelty lines.
