Rare rafflesia blooms in Mt. Kanlaon Natural Park

BACOLOD CITY — Amid continuing volcanic unrest at Mount Kanlaon, a rare Rafflesia speciosa has been found blooming inside the Mount Kanlaon Natural Park (MKNP), offering what environmental officials described as a symbol of nature’s resilience.

The Department of Environment and Natural Resources–Negros Island Region (DENR-NIR) said in a Facebook post on Thursday (July 2) that the endangered flower was discovered by park ranger Israel Malunes in Barangay Ilijan, Bago City.

The bloom measured 40.5 centimeters in diameter. Endemic to Negros and Panay islands, Rafflesia speciosa is among the country’s rarest and largest flowering plants.

Blooming for only three to five days, the flower emits a strong odor resembling rotting flesh to attract flies that pollinate it. It has no stems, leaves, or true roots and lives entirely within the tissues of its host vine.

The discovery comes as Mount Kanlaon remains under Alert Level 2 because of ongoing volcanic unrest.

Despite the volcano’s activity, the DENR-NIR said the bloom demonstrates that the protected area continues to support unique and irreplaceable biodiversity.

“This remarkable discovery is a powerful testament that even amidst volcanic unrest, the protected area remains a thriving sanctuary for unique and irreplaceable biodiversity,” the agency said.

“It highlights the importance of sustained conservation efforts and the invaluable role of our dedicated park rangers, local government partners, and environmental stewards in safeguarding these natural treasures,” it said.
