Climbing growth
Bright filtered light
Hoya australis ‘Lisa’ combines broad glossy leaves with irregular lime and cream zones, while young growth can open in warm pink tones.
Three plants in one pot give an immediately full base and more climbing tips without changing the need for an airy substrate.
What makes it distinctive
Internal variegation, a pink transition and a multi-planted base give ‘Lisa’ rich colour without a heavy silhouette.
Central variegation
Lime and cream zones appear within the green blade in different proportions on every leaf.
Pink juvenile stage
Tender blades can begin pink or bronze and change as they mature.
Three active bases
The multi-planted pot creates a full appearance sooner and allows stems to be directed in different ways.
Why you will love it: it brings warm variegation and generous volume to a small pot, with foliage that changes character from emergence to maturity.

In your space
Where it looks its best
Give it a slim hoop or discreet trellis near a bright window and guide new stems loosely without tight ties. Natural wood, terracotta and dark ceramic emphasise its epiphytic character.
Plant pairings
Plants that set it off
Pair it with other epiphytes that enjoy aerated roots and bright filtered light while changing the foliage silhouette.
Ceropegia woodii — fine trailing movement and silver patterning that brightens the composition.
Scindapsus pictus — velvety silver-spotted leaves for a rich contrast of textures.
Hoya linearis — linear foliage that creates an airy counterpoint beside broader blades.
Care at a glance
Light
Very bright filtered light. Gentle morning or late-afternoon sun after gradual acclimation.
Water
Water thoroughly once most of the mix has dried. Never leave water standing around the roots.
Atmosphere
Keep at 18–27°C with moderate to raised humidity and good airflow; protect below 15°C.
Pets
Hoyas are generally regarded as non-toxic to cats and dogs, although species-specific data are limited for less-studied taxa. Discourage chewing.
Detailed careComplete care guideLight, watering, humidity, substrate and nutrition in detail
Bright filtered light
Place it near an east- or west-facing window or behind a sheer curtain. Ample light supports compact growth and potential flowering, but abrupt hot sun scorches foliage.
The watering cycle
Water evenly and let excess escape, then wait until most of the airy mix has dried. Fleshy tissues tolerate brief dryness better than permanent saturation.
Humidity with airflow
Moderate to raised humidity supports roots and new growth, especially in small pots. Gentle air circulation is essential so leaves and nodes do not stay continually wet.
Temperature and stem direction
Keep at 18–27°C and above 15°C. Let stems trail or guide them gently around a hoop without tight ties that damage the active tip.
An epiphytic substrate
Use a highly aerated Hoya mix with coarse components and immediate drainage. Repot infrequently and increase the container only slightly once the root ball has genuinely filled it.
Nutrition and repotting
During active growth, use Nutri One, a complete liquid NPK feed with trace elements, only as directed and never on bone-dry mix. After repotting into a fresh enriched substrate, wait before feeding so nutrition is not needlessly doubled.
Botanical identityOrigin & taxonomic identityThe species, origin and cultivated selection
Accepted taxonomic identity
Hoya australis is an accepted species in the Apocynaceae. ‘Lisa’ is a cultivated variegated selection of the species and is maintained clonally from cuttings.
Native range and growth habit
Hoya australis is native from northern Borneo, Sulawesi and New Guinea to the south-western Pacific, growing as an epiphyte in tropical environments.
The cultivated ‘Lisa’ selection
‘Lisa’ is widely recognised in cultivation by its internal variegation. A breeder or crossing history has not been published with the name.

Epiphytic roots need oxygen
Hoyas often evolved on trunks or rocks where water and air alternate quickly, explaining their need for a coarse, aerated mix.
Corolla and corona are separate structures
The waxy flower typically has a five-part corolla and a second star-shaped corona in the centre, creating its characteristic double geometry.
Pollen travels in compact packets
As in many Apocynaceae, pollen is organised into pollinia joined in a specialised pollinarium rather than released as loose dust.
Variegation changes the energy balance
Pale zones contain less chlorophyll, so the plant relies more heavily on green tissue. It needs abundant indirect light, not excessive feeding that softens new growth.
Frequently asked questions
Practical answers about behaviour, common signs and correct care for this plant.
01Why did a new pink leaf turn cream and green?
Pink is often juvenile anthocyanin pigment and recedes with maturity. Judge the final variegation only once the blade has fully hardened.
02When exactly should I water?
Check deep in the mix and feel the pot's weight. Water when most of the substrate is dry and the container is noticeably lighter, then drain completely.
03Should I separate the three plants?
Not if they are healthy. The planting is designed for fullness and can remain together; separate only for deliberate propagation or when a confirmed root problem requires intervention.
04Why is it not flowering?
Flowering depends on maturity, light intensity, stable care and species. Increase bright filtered light gradually and avoid overfeeding; a young plant may simply need time.
05Should old flower spurs be cut off?
Not while they remain alive. Many Hoyas bloom again from the same persistent peduncle, so remove only tissue that is dry or clearly damaged.
06Is it safe for cats and dogs?
Commonly grown Hoyas are generally listed as non-toxic, but equally detailed evidence is not available for every uncommon species or cultivar. Keep the plant from habitual chewing because a large amount of any plant material can still cause stomach upset.
