Hoya Caudata Sumatra Information

Hoya Caudata Sumatra, or Hoya Caudata, is a vining epiphyte from the Apocynaceae dogbane family and was discovered in 1883 by Thomas Hoya. This rare wax plant variety produces green-red-tinged foliage covered in a waxy layer and silver speckles. It offers creamy to pink vanilla-scented hairy blooms.

This tropical and terrestrial plant is native to southern Thailand, Singapore, Sumatra, Peninsular Malaysia, and Borneo, where it thrives on stream beds and rocks. The word Caudata in the plant name implies ‘having a tail or caudate.’

Hoya Caudata is ideally grown in hanging baskets as it trails beautifully.
