Grammatophyllum speciosum is an epiphytic and occasionally a lithophytic plant, forming spectacular root bundles. Its cylindric pseudobulbs can grow to a length of 2.5 m. Each raceme can grow to a height of 3m, bearing up to eighty flowers, each 10 cm wide. The plant is sometimes called Sugar Cane Orchid as it resembles a sugar cane plant. The flowers are yellow colored with maroon or dark red spots. Grammatophyllum Speciosum not only produces the largest orchid flower in the world, but is also the heaviest orchid plant in the world. Because of its enormous size, it is rarely cultivated as this species is usually too large to be accommodated in most greenhouses. Cultivated specimens of this species are always grown as terrestrials, as the plants grow as both an epiphyte and terrestrial in habitat.
