Every summer, as the emerald waters and azure skies of Ha Long Bay deepen in color, mountain dragon trees (phát dụ núi) burst into bloom on the sheer limestone cliffs rising from the sea, adding brilliant splashes of gold to the UNESCO World Natural Heritage Site.

Known locally as phát dụ núi or phát tài núi ("mountain fortune plant"), the dragon tree is regarded as a symbol of prosperity, good fortune, and enduring vitality. Its remarkable ability to take root on barren limestone cliffs, withstand wind and waves, and thrive in a harsh natural environment has made it an enduring emblem of resilience and perseverance.
Each summer, this extraordinary vitality is rewarded with a spectacular floral display. The golden blossoms, like rays of sunlight resting upon the limestone cliffs, quietly cloak Ha Long Bay in a mantle of purity and quiet majesty. Set against the endless blue of the sea, sky, and limestone karsts, their radiant golden hues create a captivating contrast, transforming every vista into a living landscape masterpiece patiently sculpted by nature over millions of years.
