Grammatophyllum is a genus of epiphytic orchids that is native to tropical regions of Southeast Asia and the Pacific Islands. These plants are known for their large, showy flowers that can be up to 30 centimeters in diameter, and their long, thick stems that can reach several meters in length. Grammatophyllum orchids are often grown as specimen plants due to their impressive size and striking appearance.

Grammatophyllum orchids are relatively easy to grow and require bright, indirect light and high humidity to thrive. They prefer a well-draining growing medium, such as a mixture of bark and sphagnum moss, and should be watered regularly but not allowed to sit in standing water.

Grammatophyllum orchids are highly valued by orchid enthusiasts for their impressive size and stunning flowers. They are also important in traditional medicine, with various parts of the plant used to treat a range of ailments.
