Hayun Lagu: Growing the Critically Endangered Guam Tree
Meet the Hayun Lagu (Serianthes nelsonii), one of the world’s rarest trees and a true botanical treasure from the Pacific islands. This magnificent species represents both incredible beauty and urgent conservation need, making it a plant that deserves our attention and protection.
What Makes Hayun Lagu Special
The Hayun Lagu is a stunning tropical tree that can grow over 16 feet tall under ideal conditions. As a perennial woody plant with a single trunk, it develops into an impressive specimen with compound feathery foliage and produces clusters of fragrant white to cream-colored spherical flowers that are absolutely breathtaking when in bloom.
Where It Calls Home
This remarkable tree is native exclusively to Guam and the Northern Mariana Islands in the western Pacific Basin. Its incredibly limited natural range makes it one of the most geographically restricted trees in the world.
