Hoya imbricata is part of the Apocynaceae family and its native range is from the Philippines to Sulawesi. This true epiphyte can be found shingling in an overlapping fashion up Mango or breadfruit trees. Unlike most other Hoya, H. imbricata doesn’t have opposite leaves; one leaf remains smaller and aborts and the other leaf develops new roots at the node, under each cupped leaf there is a fine network of roots. As a new stem grows from this point, then the next leaf pair grows, one leaf dies off and the process continues. Leaves are ovate and glabrous with pinnate nerves, an obtuse apex and base.
The space between the leaves and the tree is an ideal home for ants; this symbiosis provides the Hoya protection from plant-eating enemies and a safe nesting site for the ants.
Ideally Hoya imbricata needs to be mounted on bark or balsa wood in order to grow in its natural state otherwise the cupped leaves will ball around the stem.
Each umbel holds 20 or so tiny spherical flowers which are pale yellow and fuzzy.
Genus name is new Latin, named after Thomas Hoy ( c. 1750– c. 1821), English gardener. Specific epithet comes from the Latin imbricatus meaning overlapping.
Hoya aren’t considered toxic, however, they may make your pet or child vomit if ingested, keep out of reach just to be safe.

Light: Bright indirect light, meaning the plant sees the sun for 0-4 hours per day - this could be through trees or a translucent curtain, it’s important for the plant to see the sky in order to thrive. This plant also does well under grow lights.
Water: Keep sphagnum moist at all times if your plant is mounted. If your plant is remaining potted, allow the majority of thee mix to dry out, water will usually flow through quite easily.
Potting mix: A chunky well draining mix composed of coco coir, perlite or vermiculite, orchid bark, sphagnum moss and worm castings; you could also add some horticultural charcoal to this epiphytic mix. Alternatively, you can pot in a mix of coco chips and perlite.
Fertilising: Feed your plant every few waterings during the growing season or when you observe active growth. You can dilute fertiliser to half the recommended amount but never add more.
Humidity: Very high, over 70%.
