On offer is a fully rooted, actively growing Hoya neo-ebudica currently with six leaves and an active vine.
INFORMATION ABOUT THIS HOYA:
Etymology - New Ebudic - the new name for New Hebrides (group of islands in the South Pacific in the Republic of Vanuatu
Distribution - Vanuatu and the other islands in the New Ebudic
Growth Habit - climbing and scrambling
H. neoebudica wants bright, indirect light. It can tolerate some morning or evening light but avoid hot midday sun or the leaves will yellow and scorch.
Use a very well draining soil mix and re-pot at least every other year with a coarse, extremely well draining substrate. Water thoroughly, allowing excess to drain. A waterlogged soil will lead to yellowing leaves, followed by root rot and death. Never allow the plant's roots to sit in standing water.
H. neoebudica is not hardy and foliage will burn and die if exposed to frost. It can handle continual temperatures down to 15°C (60°F) and growth will suffer in temperatures continually above 35°C .
H. neoebudica can be affected by spider mites, scale, thrips.
COMMON ISSUES WITH ALL HOYAS
I found this article in the internet ages ago and I think this is a simple, very basic and yet very helpful article regarding common issues with Hoyas.
Yellowing leaves are a sign of water stress. Yellowing that starts from the bottom means that you are overwatering your hoya. Ensure the pot has good drainage and you are using a well draining substrate. If the soil is staying too moist for too long, then you need to repot into a mix that dries more quickly.
Yellowing on the top of the plant/vine means you are underwatering. The plant is not getting enough water or nutrients.
Thin or wrinkling leaves
Wrinkled leaves may indicate the plant is thirsty and needs water. If the plant has wrinkled leaves and the soil is being kept moist it could mean the plant's roots are rotting. Gently remove the plant from its container and check that the roots are healthy.
Dropping new leaves
If your hoya is actively growing but drops any new leaves before they have fully matured it is likely a sign of water stress. Did you recently soak the plant? Or have you been letting the Hoya dry out for too long in between waterings? Try adjusting your watering schedule to reduce the large swings in conditions for the plant.
Hoya that are actively growing or about to flower require more water than a Hoya that is sitting dormant.
Slow or no growth
Hoya can be temperamental plants. A change in environment may send the plant into a partial dormancy and growth will stop for weeks or months. Give the plant time to adjust to a change in its surroundings, especially if it has recently been brought home from the store or been moved from outside in, or visa versa.
Hoya, especially those with thicker leaves, can occasionally produce foliage that is misshapen. This is normally because of stress during the production of the leaf - maybe the plant was overwatered, the temperature was especially high or low or the plant was moved into a new environment. New growth on the plant should be the 'right' shape, assuming the conditions are more consistent in future.
Vines dying back
Many Hoya send out leafless vines to seek out spots of sunlight and branches to twine and climb. Given time and light, these vines will produce leaves. However sometimes the plant will decide the vine is not viable and it will die back - if you see the tip of the vine shrivel then it is safe to cut it off.
