Hoya obovata

A climbing epiphyte with thick, rounded, often silver-speckled leaves, described by Decaisne in 1844. The most recent Sulawesi checklist treats it as endemic to Sulawesi, although Kew also lists Maluku, Thailand and Vietnam. Wild information is thin: no wild GBIF records survive the filtering, so the conditions below lean on the measured lowland tropical climate and on what is known of the genus. Grow it like a warm lowland hoya: bright filtered light, steady warmth, and a chunky mix watered as it approaches dry.

Where it grows wild

An epiphytic climber of humid tropical forest, rooting onto tree bark with aerial roots. Published habitat detail for wild plants is essentially absent; Sulawesi specimens, including one earlier misidentified as H. excavata, are known mainly from herbarium sheets. It is close to H. kerrii, which was once treated as a variety of it.

No wild records carry an elevation. Secondary sources give lowland to lower montane forest, roughly 0–1200 m, but this is not backed by a primary flora.
