Waling-Waling or Vanda sanderiana, is described as the "Queen of Philippine Orchids". One of the largest species in the world, Waling-Waling was discovered by German Taxonomist Heinrich Gustav Reicheinback in Mindanao in 1882. Since then, it has become the most sought-after flower in Mindanao. The discovery of Waling-Waling has influenced another thousand colorful and attractive vandaceous hybrids that are now part of the world's multibillion-dollar orchid and cutflower industry.
Waling-Waling, the rarest and most beautiful orchid is famous for its large and colorful hybrids. It grows on tree trunks in the rainforests of Davao, Sultan Kudarat and other parts of Mindanao. It blooms only once a year, between July and October. However, the continuous plunder of this prized specimen has brought it to near extinction.
