Phalaenopsis gigantea is a remarkable orchid species native to Borneo, celebrated for its exceptionally large, elongated leaves and impressive flower spikes. This slow-growing epiphyte produces broad, leathery foliage that can reach lengths of up to 3 feet, making it one of the largest Phalaenopsis species. Its blooms are equally striking, with creamy-yellow flowers adorned with brown spots and a delicate fragrance, emerging on tall, arching inflorescences.

This orchid thrives in warm, humid conditions with bright, indirect light, mimicking its tropical forest habitat. It prefers a well-draining medium such as large bark chunks or tree fern fiber and requires consistent moisture without waterlogging. Good air circulation and stable temperatures between 70–85°F (21–29°C) encourage healthy growth and flowering.

Phalaenopsis gigantea is ideal for collectors looking for a dramatic and unique species with bold foliage and elegant flowers. Its imposing size and beauty make it a standout specimen in greenhouses, terrariums, or spacious indoor settings.
