Hoya edholmiana

Hoya edholmiana was described by Simonsson and Rodda in 2017 from Papua New Guinea, and the single wild GBIF record comes from Morobe Province at about 1,600 m. It is a cool-growing montane epiphyte: give it intermediate days, cool nights, very high humidity with moving air, and water all year with a slight easing from July to September.

Where it grows wild

An epiphytic climber of montane forest in the Morobe highlands, on mossy trunks and branches in bright cloud-filtered light; the 2017 description places it among the cool-growing New Guinea hoyas.

About 1,600 m at the one recorded site; likely 1,200 to 2,000 m overall.
