Hoya australis R.Brown

This hoya comes from Australia and Oceania, but it has also been found in South East Asia and the Fiji Islands. It was scribed in 1830.

There are many different subspecies of Hoya australis, but the flowers are almost always the same. White corolla with some red under the white corona. The flowers are 1.5-2 cm, cup-shaped and you'll find anywhere between 10 and 40 flowers in each umbel depending on what subspecies you have. Australis flowers last about one week and have a very strong spicy fragrance, which can be nice in small doses but some australis often have several umbels open at the same time and the fragrance can be overpowering.

I was able to find descriptions of six subspecies, but I will only put the ones I have here:

This one is twining, and has both pubescent leaves (less on top than underneath) and stem. The leaves are about 4-9 cm long and 2.5-5 cm wide. It's a fast grower, but not very willing to bloom. The flowers are of the smaller ones among the australis species. Sometimes this one is sold as Hoya keysii (F.M. Bailey, 1884), but from what I have read the leaves of keysii are only pubescent on the underside of the leaves...

This one is also twining, easy to grow with smooth green/dark green leaves about 6-10 cm long and 4-6 cm wide. It's a fast grower and also a frequent bloomer.

Hoya australis 'Kapoho'

This hoya was found in a place called Kapoho in Hawaii. This is another twining, easy to grow hoya with almost round leaves. The leaves are anything from 8-12 cm in diameter, quite dark green and have visible veins. The foliage on this hoya is really beautiful! So far it's a fast grower and one can only hope it's also a fast bloomer.

This is a variegated form of Hoya australis with smooth green/white leaves that have a pink tone when young and grown in sunshine. New leaves can get completely red. The leaves are about 6-7 cm long and about 4.5 cm wide. I have not seen any flowers on my plant yet, but from what I have heard they look the same as the rest of Hoya australis. However, this is one hoya that can be grown just for the foliage. It's gorgeous!

Hoya australis ssp. rupicola (K.D. Hill) P.I. Forst. & Liddle (1991)

This hoya has pubescent leaves, both on top and on the back and they are very narrow. The leaves are rather thick, about 7-11 cm long and 2.5-4 cm wide. From the photos I have seen the flowers look very much like the rest of Hoya australis.
