Hoya irisiae

Hoya irisiae is a Philippine endemic described by Ferreras, Kloppenburg and Tandang in 2014, known from very few collections and rarely in cultivation. Nothing on its wild habitat is in the open data, so this profile is built from the Philippine lowland-to-hill forest climate and what Philippine hoyas as a group need: warm nights, high humidity, bright filtered light and an airy root run.

Where it grows wild

Assumed, as for most Philippine hoyas, to be an epiphytic vine on trunks and branches in humid evergreen forest, from the lowlands into the hills.

No elevation is recorded; the placeholder climate site sits at 9 m. Most Philippine hoyas occur below about 1,000 m.
