Growth Stages

1

Establishment

4-6 weeks

Newly potted or mounted orchid with small shoots and developing root system

Keep humidity very high (70-80%); ensure excellent air circulation; avoid overwatering; maintain cool nights (55-60°F)

2

Vegetative Growth

8-12 months

Plant develops new shoots and foliage; small pseudo-bulbs forming with strap-like leaves

Maintain consistent moisture and humidity; provide bright indirect light; fertilize biweekly with diluted orchid fertilizer; ensure good air movement

3

Pre-Flowering

6-8 weeks

Mature pseudo-bulbs present; flower spikes or buds beginning to emerge from leaf axils

Slightly reduce watering (not drought stress); provide cooler nights (50-55°F) to induce flowering; maintain humidity and bright light

4

Flowering

4-8 weeks

Multiple delicate flowers with elongated sepal tails displayed; blooms typically small (0.5-1 inch across)

Maintain consistent conditions; avoid moving plant; continue misting; flowers may last 4-8 weeks with good care

5

Post-Flowering

4-6 weeks

Flowers fade and drop; plant may enter rest period with reduced growth

Do not cut flower spikes immediately; resume regular watering and feeding; allow brief rest with slightly cooler temperatures

This is an ornamental orchid; harvest flowers by cutting entire inflorescence at base when fully open for floral arrangements (lasts 2-3 weeks in water). Leave spike on plant if still producing new buds. Do not remove flower spikes until completely withered as they may produce secondary blooms.

Fun Facts

  • 🌱 The name 'cornutella' means 'little horn,' referring to the distinctive elongated sepal tails that characterize this species, which can extend considerably beyond the main flower body.
  • 🌱 Masdevallia cornutella is an epiphytic orchid native to cloud forests of Ecuador, growing naturally on tree branches where it receives consistent moisture and cool temperatures year-round.
  • 🌱 Unlike many orchids, Masdevallia species lack pseudo-bulbs in some cases and instead have thin, creeping rhizomes; this adaptation allows them to spread across host trees in their native habitat.
