Origin and Natural Habitat
Hoya kerrii is indigenous to south-eastern Asia, but the variegated form is generally only seen in cultivation.
Plant Characteristics
Hoya kerrii ‘Splash’ has silver ‘blotches’ of variegation streaked across its leaves. The flowers are small and star-shaped, with white petals, and a raised red center.
Care Guide
Light
Hoya prefer shady conditions, and will have great colouration if kept under 60% shade cloth. It should not be kept in full sun.
Soil
Hoya requires a well-draining soil mixture with plenty of organic components. A medium with coco peat is preferred.
Water
In cultivation, Hoya kerrii can be watered well during the warmer months. However, keep this plant partially dry in winter when it is dormant, only watering if the leaves become dehydrated.
Pot size
Hoya kerrii is a vining species, and prefers a hanging basket or large pot and trellis to grow into.
Temperature
This species’ ideal temperature ranges between 20 – 30°C. It can tolerate 10 – 40°C and is extremely sensitive to frost.
Humidity
Hoya kerrii enjoys humidity, but make sure that your growing space still has some airflow, particularly in winter.
Fertilizing
Use a half-strength diluted general liquid fertilizer only during the growing season. Do not fertilize during winter. Alternatively, a small amount of slow-release fertilizer will be sufficient.
Growing season
Hoya kerrii is in active growth during spring and summer.
Propagation
The variegated form of Hoya kerrii is best propagated from stem cuttings.
Stem propagation: Using a sharp, clean knife, cut an offset about 30% of the size of the mature plant from the main stem. Let this dry for 5 days, then plant it. The best time to propagate is early spring.
