Hoya Pubicalyx 'Silver Pink' (Silver Pink hoya) care

Light

In the wild hoya pubicalyx 'silver pink' grows on the bright edge of a forest canopy, not in the canopy and not in the open. Indoors, that translates to within a metre of an unobstructed window, sheer curtain optional. Bright, indirect light intensifies the silvery leaf speckling and drives heavy flowering. Tolerates some gentle direct sun, especially morning; very bright light brings out pink and red leaf tints. Avoid scorching midday sun behind glass. The fastest test: a hand held at the leaf casts a soft-edged shadow at noon — sharp shadow means too much sun, no shadow means too little light.

Watering

Aim for when the top 3-4 cm of mix is dry, roughly every 7-12 days in growth for hoya pubicalyx 'silver pink', but treat that as a starting point rather than a rule. A south-facing summer windowsill will dry the pot twice as fast as a north-facing winter room. Lift the pot; if it feels noticeably lighter than it did wet, water it. Water thoroughly and let the pot drain, then let the upper mix dry before watering again. The thick, semi-succulent leaves make it drought-tolerant and very forgiving of occasional neglect; overwatering is the main risk. Reduce watering in winter.

Soil and pot

Hoya Pubicalyx 'Silver Pink' grows best in chunky, fast-draining epiphytic mix. Orchid bark, perlite and a little coco coir or peat (about 2:1:1) provide the airflow these roots like. Horticultural charcoal helps keep the medium fresh. It is tolerant of mix type provided drainage is excellent. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Hoya Pubicalyx 'Silver Pink' sits happiest at around 40-60% humidity and 18-29°C (64-84°F). Among the most adaptable hoyas, it does well in ordinary household humidity around 40-50% and does not require special measures. Higher humidity speeds growth, but this cultivar thrives without it, making it ideal for typical home conditions. If you keep the room above 18 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed hoya pubicalyx 'silver pink' sparingly. Feed every 3-4 weeks in spring and summer with a balanced liquid fertiliser at half strength; a higher-potassium bloom feed in late spring promotes its abundant umbels. Stop feeding in autumn and winter when growth slows. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on hoya pubicalyx 'silver pink' in the Growli community. Each is annotated with the most common cause so you know where to start.

• Faded leaf splashing — Insufficient light dulls the silvery flecks. Move to a brighter spot to restore the speckled, sometimes pink-flushed colouring.
• Overwatering rot — Soft, yellow leaves follow a mix kept too wet. Let the upper layer dry fully between waterings and use a pot with drainage.
• No blooms despite size — Often too little light or removal of the flower spurs. Brighten its position and never cut off the old peduncles, which rebloom each year.
• Mealybugs and aphids — Attracted to fast new growth and flower nectar. Wipe with insecticidal soap or alcohol and isolate until the pests are gone.

Propagation

Extremely easy from stem cuttings with one or two nodes; root in water, sphagnum moss or a perlite mix in bright indirect light. Roots usually appear within 2-4 weeks thanks to its vigour, making it one of the most beginner-friendly hoyas to propagate. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Hoya Pubicalyx 'Silver Pink' is pet-safe. The genus Hoya is ASPCA-listed as non-toxic to cats and dogs (Hoya carnosa, the wax plant, is on the ASPCA non-toxic list). Hoya pubicalyx 'Silver Pink' is a cultivar of this genus and shares the pet-safe stance; large ingestions may still cause minor, transient stomach upset. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
