Help me ID my hoya please :)

amelianzDecember 7, 2012

HI all,
I have in the last few years inherited two Hoyas from my deceased grandma, one of which I quickly identified as carnosa (pretty sure ;) and have just had to transplant it as it was seemingly becoming hollow and brittle on some stems to roots and generally unhappy. I have cuttings and feel it should bounce back. My inherited house plants have seen me go mad with house plant and now specifically Hoya fever :S

BUT this photo is of my thinner leafed, charcoal/black w crimson inside flowered Hoya! I have just got hooked on the forum and was trying to find out if it was 'Black dragon'? because it certainly is black! I am not sure whether certain spears are black w black leaves or they turn green later, I think there is a mix of that going on? Its really going for it now its summer ( I live in NZ and it is kept inside beside a window) I have moved it into slightly more shade as I think the sun was starting to burn it! Three clusters of flowers and two more buds on the way. My grandma would have had this darker one for at least 10 years probably longer. Mum said the Carnosa is probably older than me (haha 25) :D

Sorry the photo is so bad, no camera atm. Hopefully you guys can help me :)
Kind regards,
Amelia :)

Your plant is a variety of Hoya pubicalyx, figuring out the cultivar name isn't really important as they all require the same care. If I had to guess I would say Hoya pubicalyx 'Royal Hawaiian Purple'.
Hoya pubicalyx is a close relative of Hoya carnosa, pubicalyx coming from the Philippines where as Hoya carnosa is from China.
Hoya pubicalyx 'Black Dragon' is a new introduction that was collected in the wild and not simply a horticultural variety. It has only been available for a few years so it's not a common plant at all. The leaves of this one are always solid green unlike many of the other Hoya pubicalyx varieties.

I think it's a nice photo, Amelia. You certainly have some gorgeous blooms there. I would be super happy to get such charcoal-y flowers out of my publicalyx. :)

Your description of the leaves as starting out dark also fits with Mike's RHP postulation. This plant is known for lots of chocolate and wine colored leaves.

As Mike says, Black Dragon's leaves are pretty but a very boring flat green. It might not even turn out to be a publicalyx. Also, it doesn't always bloom black either, as some of us have been disappointed to discover. Bloom color can fluctuate wildly depending on the plant's conditions.

If you really do have a RHP, it's a very interesting plant in this respect and often shows vivid watercolor splashes of various colors on single flowers, or very different colored blooms right next to each other.

Happy growing and thanks for sharing your Hoya story with us!
