|}}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 known Phalaenopsis species.[1]Species Description- 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- Phal. gigantea var aurea: has a brighter yellow background color throughout the sepals and petals [1]
Growing Conditions- 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]
