Hoya australis ‘Lisa’

Origin of Hoya australis ‘Lisa’

‘Lisa’ is a variegated sport of Hoya australis subsp. tenuipes, and the cultivar name was established in 2007. It may have been selected in Thailand. The wider species occurs from northern Borneo and Sulawesi through New Guinea and Australia into the south-western Pacific, including seasonally dry tropical habitats.

Care for Hoya australis ‘Lisa’

• Light and colour: Choose a bright position with harsh afternoon sun filtered. The pale centre contains less chlorophyll and can scorch against hot glass. Keep the green sections in bright filtered light.
• New foliage: Pink colour on young pale sections is normal and fades as the leaf hardens. Remove only fully green reverted runners.
• Water and roots: Once the upper mix is dry, soak the root ball fully and drain it. Slower variegated roots are less forgiving of a cold saturated centre. Pot the vine into an airy bark-based mix that wets evenly, leaving air spaces around the roots. Use a pot only slightly larger than the healthy roots; excess mix stays wet around slower variegated growth.
• Support: Guide the growing tip onto a firm support while it is young. Keep the growing point facing the window as it climbs.
• Temperature and airflow: Keep the plant away from radiators, hot vents and cold glass. Warm conditions without sudden temperature changes help variegated leaves expand cleanly.
• Feeding: Feed ‘Lisa’ lightly after watering while a new leaf or side shoot is forming. Pause when no new growth is visible or the root ball dries more slowly. Fertiliser supports healthy growth but does not alter the variegation.
• Flowering and pruning: Keep established flower spurs when shortening the vine; the same peduncles can produce later clusters of white flowers.

Common issues with Hoya australis ‘Lisa’

• New growth loses the expected pale centre or marginLikely cause: A bud with a different balance of green and pale tissue has taken over the runner.What to do: Keep any balanced growth. If two or three leaves remain all green or almost all pale, cut the runner back to the last node that produced a balanced amount of green and pale tissue.
• Bright tissue tears or browns during leaf expansionLikely cause: The plant was pushed into stronger light before the new leaf hardened.What to do: Protect the pale tissue from hot glass and avoid heavy feeding while the roots recover. Keep a firm dry leaf; remove it only if the patch becomes wet, soft or rapidly larger.
• Distorted new leaves and sticky nodesLikely cause: The distorted tip may be under attack from sap-feeding insects or mites.What to do: Separate the plant and inspect soft growth and hidden leaf surfaces under magnification. Rinse off visible pests, patch-test insecticidal soap, and follow its label for repeat timing; stop if the pale tissue develops marks.
• Wide gaps and smaller leaves appear on new growthLikely cause: The growing tip is too far from the window, or wet roots are slowing the vine.What to do: Move the tip into brighter filtered light and check the centre of the pot before watering. New growth should form firmer leaves with shorter spaces between them.

Hoya australis ‘Lisa’ and pet safety

Hoya australis ‘Lisa’ is treated as non-toxic to cats and dogs. Chewing leaves or stems can still cause temporary drooling, vomiting or diarrhoea. Keep the plant out of reach of pets that chew foliage, and contact a veterinarian if symptoms are severe or persistent.

A southern Hoya called ‘Lisa’

The Latin australis means southern and refers to the species range. ‘Lisa’ is the established name of this variegated sport.
