Phalaenopsis gigantea

Phalaenopsis gigantea is named for the giant size of its leaves, which can grown over 2 feet in length on a mature plant. This orchid is endemic to Borneo and was first described in 1909. It is the largest Phalaenopsis species. [1]

Species Description[edit]

Phalaenopsis gigantea seedling
Phalaenopsis gigantea inflorescence
  • A very short monopodial stem with 5-6 large silvery-green pendent leaves that can measure over 60 cm across
  • flowers are ~5 cm across (up to 6.5 cm), cream background with raised red-brown spots, and varying degrees of green around the column, waxy
  • Mature, specimen-size plants are capable of producing hundreds of flowers on pendent, branching inflorescences reaching 40 centimeters
  • blooms have sweetly fragrant citrus scent
  • flowers can last many months
  • inflorescence can rebloom over many seasons [2]
  • Although widespread belief that this orchid takes anywhere from 8 to 12 years for a seedling to reach flowering size, it may be possible to flower seedlings in 4 years with ideal culture [3]

Species variants[edit]

  • Phal. gigantea var aurea: has a brighter yellow background color throughout the sepals and petals [1]

Growing Conditions[edit]

  • warm to hot growing orchid[2]
  • although not difficult to grow, (gigantea) seedlings take significantly longer to reach maturity than other species
  • particularly susceptible to rot if water gets trapped between the leaves
  • allow potting media to dry out completely between watering
  • Phal. gigantea needs its entire root system to keep the large leaves hydrated, so as a result is very sensitive to getting its roots disrupted
  • prefers higher light than most phalaenopsis[1]
