Hoya mitrata

Natural range and habitat of Hoya mitrata

Hoya mitrata is native to southern Thailand through western and central Malesia. It grows on trees in humid tropical forest, where mature leaves can sit closely against the support.

Care for Hoya mitrata

Provide a broad slab or stable trellis and leave space for the mature leaf clusters, which can form sheltered pockets called domatia.

Keep it in bright, indirect light, with protection from intense direct sun. Mild early or late sun is suitable after gradual acclimation.

Keep the plant between about 16 and 24 °C during normal growth, with protection from sustained temperatures below 10 °C. Keep humidity around 60–80%. Keep a gentle flow of air around the foliage, for normal growth.

Use an airy, freely draining potting mix. Check beneath the surface and water after much of the root ball has dried, before the mature leaf pairs lose firmness. Soak the full root ball and let the excess drain.

As growth slows in cooler or lower-light conditions, extend the drying interval and reduce feeding frequency.

Use a complete fertiliser at modest strength while runners are extending.

Repot when the root ball becomes crowded or the potting mix breaks down.

Root a healthy section of the plant stem with at least one node, keeping the cutting warm through the rooting stage.

Health checks for Hoya mitrata

Paired leaves crease against a narrow support

Developing domatia need a broad, stable surface with room for the leaves to press together. Leave mature pairs in place and guide the next flexible shoot onto a slab with room for the leaves to press together.

Moisture or pests collect inside the leaf pairs

The sheltered space formed by mature domatia can stay damp and conceal scale insects or mealybugs. Inspect without prying the leaves apart, keep water from pooling there and treat only after confirming the pest.

Mature leaf pairs soften while the pot stays damp

Softening in the mature domatia-forming leaf pairs above wet substrate points to reduced root function. Delay watering, check the coarse mix and remove black or soft roots before repotting. Firm marks on older broad leaves may remain after physical damage or oedema; clean new growth shows that the cause has passed.

Hoya mitrata is non-toxic to people and pets

• This plant is non-toxic to people, cats and dogs.
• Chewing a large amount can still cause an upset stomach.
• If a large amount is eaten and symptoms continue, contact a veterinarian or medical professional.

Why is it called Hoya mitrata?

Hoya honours the English gardener Thomas Hoy. Mitrata means mitre-shaped and refers to the paired leaves that can form domatia on mature plants.

Robert Brown established the genus Hoya in 1810 in Prodromus Florae Novae Hollandiae, page 459.

Arthur Francis George Kerr first described Hoya mitrata in 1940 in Hooker’s Icones Plantarum, volume 35, plate 3406.
