Stanhopea tigrina care and size
Stanhopea tigrina is one of the most architecturally unusual orchids in cultivation — its inflorescences drill downward through the basket medium, meaning a conventional pot will smother the bloom before it opens. Size is modest in footprint but the plant grows with surprising speed; documented growers report flowering from an 8 cm pot within two years, with five simultaneous inflorescences. The care envelope is narrow: heat, dryness, or stagnant air will kill it faster than most growers expect.
Evidence
- Temperature requirements documented by botanapp.com (Aug 2026) sit at 18–27°C (65–80°F) daytime and 13–18°C (55–65°F) at night — the cooler night differential is critical for initiating spike development.
- Humidity is non-negotiable: PlantCultivar (Sep 2026) specifies 60–80% as a hard floor, noting the plant's cloud-forest origin.
- Watering follows epiphytic logic: water thoroughly, drain completely, allow the top 2–3 cm to approach dryness before rewetting.
- The same source records individual flower width reaching 15.5 cm (6.1 inches) on the var. nigroviolacea forms, with fragrance profiling as chocolate and vanilla, shifting to a faint mothball note as blooms age over their typical 2–3 day window.
- Above 29°C (85°F), increased shade, airflow, and humidity must compensate or leaf tissue burns.
