Hoya carnosa ‘Speckles’

Origin of Hoya carnosa ‘Speckles’

The name ‘Speckles’ is used for a cultivated Hoya carnosa. It is still unclear when or how this cultivated form was selected and introduced.

Hoya carnosa occurs naturally from southern China to Laos and southern Japan to Taiwan.

Care and growing tips for Hoya carnosa ‘Speckles’

• Position and growth: Place ‘Speckles’ in bright indirect light, protected from hot direct sun. Let the stems trail or guide them around a hoop.
• Temperature and humidity: Keep it around 16–24 °C and avoid prolonged temperatures below 10 °C. Aim for 50–60% humidity with gentle airflow.
• Watering: Grow it in a chunky free-draining mix. Water when the pot feels light and the mix is nearly dry through most of the root zone, then wet the entire root ball and drain it. Slower growth or lower light means a longer drying interval.
• Feeding: Use balanced orchid fertiliser at moderate strength about every two weeks while new growth is active, pausing when growth stops.
• Repotting: Move up one pot size once roots have outgrown the container, or replace deteriorated mix without increasing pot size when the roots still fit.
• Propagation: Root a healthy one- or two-node cutting in a lightly moist, airy medium and keep it warm in bright indirect light until established.

Problems and solutions for Hoya carnosa ‘Speckles’

• Wilting while the pot stays wet: Persistent wetness can damage roots. Drain trapped water and inspect roots if decline continues. If you find a small amount of root rot, use a clean, disinfected tool to cut the soft roots back to firm, healthy tissue. Throw away the rotten roots and old mix. Repot in fresh, airy mix, using a clean pot just large enough for the roots that remain. The pot must have drainage holes. If decay is widespread, save only healthy stem cuttings. Discard the plant if no healthy stems remain, and disinfect your tools afterwards.
• Leaves become soft in a dry, light pot: Check whether the mix around the roots is dry. If the root ball is dry, water thoroughly and drain. If the leaves still wilt after watering, inspect the roots. Avoid repeated watering while the roots are still wet.
• New fine speckling (stippling) or webbing: Pale speckles are normal on these leaves; look for new damage around them. Inspect damaged leaf undersides with magnification; tapping a leaf over white paper can help locate mites. Confirm spider mites before treatment. Isolate the plant, gently rinse both leaf surfaces and let water drain. Recheck every few days and repeat rinsing while live mites remain.

Hoya carnosa ‘Speckles’ 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.

Hoya carnosa: where the name comes from

Hoya honours the English gardener Thomas Hoy. The Latin epithet carnosa means fleshy and refers to the thick leaves.

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

Carl Linnaeus the Younger first described it as Asclepias carnosa in 1782 in Supplementum Plantarum, page 170. Robert Brown later placed it in Hoya as Hoya carnosa in 1810 in Asclepiadeae, page 16.
