Hoya krohniana

A small epiphytic Hoya with heart-shaped leaves, described in 2009 from a cultivated plant thought to come from the Philippines. It has no published type locality or wild habitat notes, and a 2022 study suggests it may be only a form of Hoya lacunosa. The best guide to its needs is therefore lowland Southeast Asian forest-epiphyte conditions like those of H. lacunosa: warm, humid and bright but not harsh.

Where it grows wild

Its wild habitat has never been described. It is assumed to be a creeping and climbing epiphyte of humid lowland forest like its close relative H. lacunosa, rooting along its stems on bark.

Unknown. No wild records with elevation exist, and the type description gives no locality.
