A stunning Preah Trahoeng giant orchid, known as the world’s tallest orchid, is blooming for the third time in Siem Reap.
This extraordinary event took place at the Sok An Phnom Kulen Orchid Research and Conservation Center, nestled within the Preah Jayavarman-Norodom Phnom Kulen National Park.
First planted in October 2018, the rare orchid has amazed garden enthusiasts by producing five flower stalks at once, an event never seen before.
The Preah Trahoeng orchid, also called the Giant Orchid, Tiger Orchid, or Sugar Cane Orchid, is native to Cambodia. It can rarely bloom, but when it does, its flowers last between two to three months.
The orchid’s blooming history includes a single flower stalk in April-May 2021, followed by another one in April 2024. Now, in April 2025, it has bloomed again with five flower stalks, creating a breathtaking sight. This remarkable achievement was reported by the Ministry of Environment.
The orchid, scientifically known as Grammatophyllum speciosum, is native to Cambodia and was once found in the Cardamom mountain range of Koh Kong province, as well as in the Dangrek mountain range of Preah Vihear and Siem Reap provinces.
This orchid holds the world record for being the tallest in the world, as recognized by the Guinness Book of World Records. Some plants have reached up to 7.62 meters (25 feet) in height and can weigh up to two tonnes. The orchid’s flower stalks can grow to two meters long and hold between 80 to 100 beautiful flowers.
Cambodia is home to over 500 wild orchid species, with more than 200 documented for conservation and study. The Sok An Phnom Kulen Orchid Center, established in 2018 and officially opened in August 2023, is dedicated to preserving and restoring these rare plants.
It focuses on research, breeding new orchid varieties, and conserving endangered species.
In addition to its important conservation work, the center also plays a role in educating the public about Cambodia’s wild orchids and biodiversity. Visitors can explore the scenic beauty of the center, which offers a fantastic spot for ecotourism and relaxation.
Currently, the garden is being enhanced through a partnership between the environment ministry and Soma Group.
