I don't know how to post a pic here but if anyone has an idea about it id appreciate it thanks |
| Neutral | On Apr 17, 2016, smileclick from Sydney, I saw one of these Hoyas in flower at the Royal Botanic Garden, Sydney today (mid autumn), photo attached. It was growing under branches of a low tree, and had a draping habit. The vines would be about 4 metres/12' long, and there were large gaps between leaves. The flowers were beautiful half spheres, and had a strong fragrance, the same as my commonly grown indoor plant, dracaena fragrans' flowers - a strong, sweet almond fragrance. Both plants' fragrance would be overpowering indoors - I needed to cut down sections of my dracaena fragrans flower spikes to reduce the fragrance's potentcy, but it would be a shame to do the same with this Hoya. |

This plant, Hoya australis ssp. australis, has pubescent leaves (soft tiny hairs). To me, the underside of the leaves feel even softer and fuzzier than the top. My plant is small and hasn't bloomed yet, but I look forward to seeing signs of peduncles, buds, and especially those beautiful fragrant blooms! |
| Neutral | On Sep 9, 2007, palmbob from Acton, CA (Zone 8b) wrote: This is one of the more arid tolerant species, needing very little humidity in its care (unlike the majority of species which prefer some humidity). It is one of the more ideal Hoyas for those with cactus collections who want a Hoya in their succulent cold frames. |
| Neutral | On Dec 7, 2005, Hoyamoyen from Aarschot, There are more than one subspecies of this Hoya. |
