Did you know Phalaenopsis gigantea is a specie endemic to the island of Borneo first described in 1909. It is the largest leaf phalaenopsis that exists in nature!

These are found in warm climate and must be grown in warm temperature to get optimal growth. Spikes are multiflora and flowers are waxy, long lasting, sequential and fragrant!

💚Difficulty: Advance (species) - Try a hybrid with gigantea parentage if you are new (search gigantea in the search bar)
🪴Size:  Very Large, flat or pendant growth,  recommend hanging / mounted
🌸 Blooms: Fragrant, ~4.5cm, sequential, can pendant incredible multifloral blooms (20-30) when mature
🌱 Grown by: x sib
🧬 Genetics: subg-polychilos
 Note: The roots are gigantea are typically slimmer, more wirey than a typical hybrid phalaenopsis. While it may not look like in abundance, their roots are healthy. (2nd last photo) They are extremely slow growing and will take much longer growth period to reach the same abundance of roots as other phalaenopsis (last photo), which makes it more difficult to cultivate.  

Culture and Care Information

*Cultural and care information is based on average Phalaenopsis subg-Polychilos hybrids, use it as guide and should be adapted to suit your environment. Important to understand if your hybrid has subg-phalaenopsis genetics and adjust as needed.

🌡 Temp: Intermediate-Warm to Warm/Hot (20-32°C day - 18-24°C night) 18-25°C is acceptable range for most indoor growing, especially hybrids, with 4-6°C difference day/night. Warm to hot temperature helps induces spike (flowering)

💧 Water: For Polychilos - Wet to almost dry cycles, complete dryout occasionally but not necessary especially in vegetative (growing) stage or warm to hot temp.  When dry, soak with room temp or warm water until fully saturated for 2-24hours. Repeat when dry (winter) or approaching dry (summer/warm)

When roots are abundance can stay more moist. Reverse Osmosis / Distilled or Rain water is best. DO NOT use ice cubes.

If hybridized with subg-Phalaenopsis - Give complete dryout or root may rot, depending on the % of polychilos-phalaenopsis genetics. Safer to allow dryouts.

☁️Humidity: 30%+min for hybrids (40-60% optimal)

💡 Light: Bright indirect (East Morning or Sunset Light direct, Mid-summer day indirect) year round.  Artificial supplementary light recommended in winter or low light homes. 10-12 hour light period to induce continuous flowering. 

🌰Media: Our preference is top 3" Sphagnum Moss & Leca bottom combo. Moss/Bark mix also works, prefer slightly higher water retentive media than regular Phalaenopsis as they like to stay slightly moist.

🧪: Fertilize: When it's actively growing in vegetative stage - typically when a top leaf emerges and growing. We recommend MSU & Marphyll rotation in low dosage every other watering and allow water flushing in between.
