Guide

The species-level account. Cultivar pages build on this and say where they differ.

Hoya linearis is an epiphytic subshrub from the cool, humid montane forests of the Himalaya and southern China, where it hangs from branches with trailing, needle-like foliage. Grown in an open, fast-draining epiphyte mix with good airflow, it drains quickly and rots if left sitting wet, so let the mix approach dryness between waterings and water only when the top inch feels dry. It prefers bright indirect light and consistently high humidity rather than direct sun.

ToxicityAuthoritative · species

Toxic to cats & dogs & humans

Apocynaceae frequently contain cardiac glycosides and irritant latex; treat as a potential hazard. This is where toxicity lives: every cultivar of this species inherits it and none can override it.
