This species is the only native, epiphytic, yellow flowered rhododendron in Taiwan, and is scattered in the fog forest belt of the island at an altitude of about 1,500 to 2,500 m (4,900 to 8,200 ft).

The wild community was assessed as "near-threatened" in the Taiwan Red Book of Vascular Plants in 2017.

The specimens collected by Hayata himself, Kawakami Takiya, and Mori Ushinosuke from Yushan, Luandashan and other locations in Taiwan were published as a new species in Volume 30 of the Journal of the College of Science, Imperial University of Tokyo.

[2] When Ryozo Kanehira published "Taiwan Tree Chronicle" in 1936, in addition to citing the results of Hayata in 1911, he also added that the flower color of this species was white to pink.

[5] Flora of Taiwan (Edition 2) in 1998 only accepted the scientific name originally published by Hayata, and clearly described the bright yellow corolla of this species, without mentioning other flower colors.

Normally, they are attached to large trees or rock walls, including to the branches of the Taiwan red cypress (Chamaecyparis formosensis Matsum).

For example, in 2018, Lei-Chen Lin team from Chiayi University in Taiwan worked with Sun-Link-Sea Forest and Nature Resort Corp., to cultivate seedlings.

[6] Another example comes from Ya-Ling Ho and Yue-Ken Liao’s team at Chiayi University, which used plant tissue culture technology in 2020 to promote bud reproduction with growth regulators such as isopentenyl adenine, and thereby accelerate the growth rate and yield of seedlings.
