This photograph from a resort garden in Bukit Tinggi, Malaysia is courtesy of Lindsay McGhee, a UBC biology student. Lindsay is working with me on the garden's John Davidson project. Thank you, Lindsay!
If you attempt a search for images of Hoya pubicalyx, you are likely to find photographs of the red- to dark-coloured cultivated forms of the species, e.g. Hoya pubicalyx 'Silver Pink'". However, I am fairly certain that white to pink is the typical colour range for the flowers of this species in the wild.
For an introduction to the diversity within the genus Hoya, visit the online photograph gallery of the International Hoya Association. Similarly, a written introduction to the genus Hoya in Singapore and Malaysia is available from the Nature Society of Singapore.

Yes! Never thought I'd see this plant on this web, but I'm so glad. It has been a mystery house plant with my mother for years, 20yrs? About 6yrs ago I took a cutting and just this past year it finally flowered, never before in her care. I find the trick is to let the tendrals grow and 'reach' out. Then after leafless tendral is about 2feet long and summer arrives, the flower peduncles emerge. Yay!

The plant looks more like Hoya carnosa to me, though without seeing the whole plant, I couldn't be sure. If I'm not mistaken, the leaves of H. pubicalyx are longer, smoother and have more silver markings. I'm also relatively certain that its flowers are generally darker than the common wax plant's. But I also know that hoyas are a variable lot, with those in cultivation not necessarily adequately representing what has been described botanically.
My grandmother supplied me with my first wax plant--H. carnosa--when I was about 13. She was responsible for starting me off with a number of great plants (including Schlumbergera, Rhipsalis, Haworthia and Aloe). I was amazed at their ability to survive my teenage neglect (grandmothers are smart). I recall marvelling at the sudden appearance of the enormous, umbellate inflorescences of the hoya, and their cloyingly sweet fragrance. I suppose that's one of the hallmarks of being a teenage boy: not noticing that things are changing until something really obvious happens.

great pic of hoya flower but i agree with Douglas, that its most likely form of H. carnosa...He hit the nail on the head with the description of pubicalyx...here is a very detailed site of many acurate hoya varieties and pictures here: http://www.myhoyas.com/index%20ENG.htm
Hope that helps in identifying hoyas correctly.

Hi I've always been facsinated by the amazing Hoya. My mother-in-law had one for 32 years and it never flowered. I was told there were a male and female plant. Hers was supposedly the male. I live in Victoria Australia and would like some advice on which the best to grow in our climate.
I do have a type of hothouse, it is not the best
but will have to do. Please help me to grow lovely hoyas. Thank you Jan McEvey

We have a plant for 10 years and this morning we were surprised by a lovely flower. I will post a picture soon.

I Had a Hoya plant that flowered every year and the Aroma was simply awesome. As I moved from Winnipeg in the winter I couldn't transport it here. I would love to get one again any suggestions. Thanks John
