We offer several sizes. The largest ones are specimen sizes that we have been growing for over 27 years. We will send photos if requested. For smaller pot sizes, please see Item #13834, Phal gigantea 'Phoebe' x 'Hyperion.'

As for the large size, these are very big with HUGE leaves (the largest plants have nearly a 4-foot leaf span). Considered extinct in northern Borneo. Potted in coconut husks. Grow shady and warm. Call for leafspan. Packing/shipping within the continental U.S. will be quoted. The smaller ones are a cross between two of our best. They are very vigorous. Amazing plants!
Intro:Phalaenopsis gigantea is native to Borneo. This plant can be found growing in the tops of trees with the roots sometimes reaching into moss. Humidity is high, and rainfall is copious, although there is a drier season usually towards the middle part of the winter. Generally the plants grow with steeply tilted leaves to shed water in order to prevent crown rot from occurring. The flowering season is heaviest in the summer; the plant can bloom from 4-6 months at a time. The colors vary from a yellow background with mahogany spots to a light, whitish pink with dark purple spots, which is the most common variety. The largest plants we offer are 22 years old! We have tended to them carefully from seed all these years. Smaller plants are sib crosses between 2 of our best. Please e-mail or call for leaf spans.
Light:Phalenopsis gigantea likes average phalaenopsis light conditions. East windows are good, or a diffused light area in the greenhouse is excellent as well. They do very well under artificial lights also.
Humidity:Grow in high humidity: 50-70% is ideal. Slightly less in the winter is acceptable.
Water:Gigantea prefers very clean water, such as rainwater, distilled, or reverse osmosis. That's exactly what they get in nature and if your municipal well water has a pH over 7.5, your water is too hard for this plant, and it will not do well. Water as the plant approaches dryness, but do not let the plant totally dry out between watering.
Fertilizer:We highly recommend using Green Jungle Orchid Food, especially formulated to work with rain, distilled, reverse osmosis water or water low in alkalinity. Fertilize with Green Jungle every time you water if plants are planted in bark. Be sure to flush the mix with clear water only once per month to prevent fertilizer salt build up. For plants in moss or mounted on slabs feed every third or 4th watering as the moss holds a lot of nutrients.
GrowMore 20-10-20 Ureafree for municipal or well water. Use at the rate of ½ teaspoon per gallon. If using GrowMore with rain, distilled, or reverse osmosis water, add back in 5 - 10% municipal or well water to supply the necessary calcium and magnesium. Fertilize every other watering in the summer and every third watering in the winter.
Flowering season usually begins in late spring, spikes can be seen to be emerging, and they will flower out in mid summer to fall. If plants are not flowering for you, they are not big enough to bloom, or are not receiving enough light or cooler temperatures to initiate blooming.
Very sensitive to repotting. This plant does not like to have its roots disturbed. We recommend you plant in a mix that will last at least 2-3 years, or a mix that is not hard on the plant when repotting. Do not use osmunda. The mix should fall off the roots easily. A good mix is either sphagnum moss in clay pots (plastic pots when the plants are smaller) a coconut-peat mix, using cocoa-peat with 50% perlite added for drainage. Be careful when handling the roots so they do not crack, for when a number of the roots crack, it seems the whole plant becomes effected. The plant may spiral downwards, or take a long time to recover. Keep dry after first repotting, not watering for at least two weeks, and for the first couple of months, be careful not to keep the plant too moist. Preferably grow this plant with the leaves angled downward to facilitate drainage out of the crown. The best potting mix is either a large bark mix or coco husk chunks.
