I have several different kinds of these, some of which have bloomed & some which NEVER have even though they are over 3 years old.
Anyway, thought it would be interesting to see a few of the blooms close up together to compare. Here are some shots I took. (Wish I could do close-ups like Ann & Christina), but here is my attempts anyway.
Hoya pubicalyx cv 'Bright One'
I got this hoya at the Fullerton arboretum. It was labled Hoya 'Dapple Grey'. I am not sure if it is a carnosa or pubicalyx, and have been told it must be H. pubicalyx 'Pink Silver', So I really have no idea, but I love it.
Same one with better shot of the flower in comparison to my hand. Big ens aren't they?
An attempt to show several of them together.
First one is that "Dapple Grey'
then is 'Red Buttons'
then is one I just got labled H. pubicalyx 'Splash'
(I think it is 'Royal Hawaiian Purple' )
Then is 'Bright One'
Here you can plainly see the the difference between "Red Buttons' and the 'Splash" one as on RB the little coronas are all that cranberry red, where on the other...they are whiteish. Sometimes on the other they have mixed ones.
Here you can plainly see the difference between the one labled 'Dapple Grey' (but what I think may be 'Pink Silver') and 'Bright One'.
Here they are all together again.
And this is a poor picture, but here are just the flowers
This is H. pubicalyx 'Reva' that has never bloomed for 3 years in spite of lots of TLC, Messenger, Eleanor's, and bloom fertilizers.
Hoya pubicalyx 'Red Buttons' flower
That's all for tonight. I may have another couple I can get tomorrow. I will try to get a good shot of the one labled 'Splash'
Marcy
Marcy those are the best comparison photos I've ever seen. Does the H. pubicalyx Bright One give you any trouble? It's been a pain for me. I've had to re root it twice.
I'm pretty sure too that your "Splash" is actually RHP.
My Dapple Grey cutting crapped out.
I have "Reva" too and she dropped her first buds. Waiting for it to try again and then I will get a photo. Will probably turn out the way my STUPID Chimera did. DH goes, oh, ANOTHER Pink Silver.....
Thing I read about the Reva variation was that the leaves were supposed to be heavily speckled and so dark they almost look black. That didn't make me too happy as I haven't seen any dark, dark leaves or dark vines shooting out...
I think some of those photos need to go in the Plant Files!
Susan
I agree with Susan! Those pictures need to go into the Plant Files. Good job Marcy. Wonderful photos and glorious blooms.
Ann
The photos are GREAT!!! What a job! The only difference I can really tell between the 'Royal Hawaiian Purple' and 'Red Buttons' is that the RHP has longer/bigger leaves than the other....
In this case, I have to say I agree with David Liddle who calls them all H. pubicalyx. Period. Full Stop. Like the H. carnosa...the cultivars have been around so long, making babies (seedlings), sporting etc. etc. etc....who knows what they really are. I was given a 'splash' which turned out to be a beautifully leafed 'Pink Silver'. So many monikers are slapped on these oldies-but-goodies...that...who knows.
All I know is that I love them...they are so faithful, so hardy and so beautiful! Shall we make this a thread of H. pubicalyx cultivars...? Good start, Marcy!
Great pictures of some gorgeous plants, Marcy.
Yes Marcy, that is very well done. And how great to have such big flowering plants that you can spare a couple of peduncles for photographys sake..
WOW, Marcy! Fabulous hoyas and fabulous pictures! I agree with what's already been said - your pics should go in PlantFiles!
B
Marcy very good photo. It is nice to see them all together to get a comparison.
Beautiful pictures, and I agree - thanks for sacrificing your peduncles for the sake of our education. Question from someone who would never do such a thing: If the just the tip of the peduncle is cut off, or falls off, will
the remaining part continue to flower?
OH YES...the plant will produce another and more! Some hoyas drop their peduncles once it has bloomed.
This is a shot of the leaves on the one called H. pubicalyx 'Splash'. I guess they named it that because of these dense markings "splashed" all over them.
And these are the new leaves on the same plant. They always start out very dark maroon colored like this. That is another reason I suspect it is R. H. P.
Marcy... I was looking at a tray of H. pubicalyx 'RHP' small plants just today. There is one that has really really heavy silver splotches on it...and I know it is RHP...and it is only one plant out of the 8 I rooted. So...this tells me it is something genetic that can happen to any of the cultivars at any time.
'RedButtons' and 'RHP' are very similar (or can be) in the blooms. I can only tell the differnce between the two by the leaves: 'Red Buttons' leaves tend to be smaller...shorter and fatter which 'RHP's leaves are longer, bigger.
My new one...'Bright One' has not stopped blooming all summer!! And the leaves are much more H. carnosa looking than the other H. pubicalyx...rather rounder than longer.
Carol, I seem to recall reading somewhere that the individual blooms on the 'red buttons' were smaller than the 'RHP.' Is this the case?
Ann
Dunno. They sure look alike to me. I have had umbels from both, side by side...and I could NOT tell the difference (and boy, did I feel stupid). I send the photos to Ms. Burton, whom I respect totally for her prowess in taxonomy and identification...and she told me the leaf size thingy. I have gone by that ever since.
Take a close look at the above photos 4&5. My Red Buttons flowers are actually smaller and more consistantly have very maroon colored coronas. The one I think is RHP flowers are larger and have white coronas, altho I have seen some that have maroon coronas as well as white ones. Sometimes a combo of both on one flower.
At least this is my observations on my own plants.
Marcy
OK, I am really losing my mind. It was right here on Marcy's thread that I saw the difference.
Thanks for clarifying! Did anybody ever post photos of differences between leaves? Marcy, if it hasn't been done, would you mind posting pictures of the different leaves for comparison?
Thanks!!
Ann
This is an open letter to all you ladies and gentlemen who are buried in a fog of confusion about all these differently named H. pubicalyx and H. carnosa "sports, mutations or whatever you want to call them. I'm with Carol and David Liddle. A pubicalyx is a pubicalyx species and a carnosa is a carnosa species, no matter what kind of fancy name is tacked on to them. Just like our children who are born of the same parents but never look exactly alike, the same applies to the plant family. The exceptions are the ones called chimera, Hawaiin Royal Purple, and Red Buttons, and the look alikes that have cropped up with at least a dozen different names in the past 5 years, basically all mutations that came from an original mutation. These are the 3 that I know of that are composed of two chromosomes and have the ability to mutate into, not just a little different looking but a whole lot different looking, even among cuttings taken from the same plant. ...No matter, they are still of the H. pubicalyx species. I don't know off hand if any of the carnosa's have more than one set of chromosomes, I don't see any indication of it. Outside of smaller or larger flowers, smaller or larger leaves, and different colors, all carnosa's that I have seen look basically alike.
About 15 years ago the IHA set up a plant registry to try to register these plants that were evaluated as something with a real difference. In a very short time we were inundated with photos of dozens of carnosa's and pubicalyx..all the same but with different names, some a little different but never enough to be classified as really different and so not eligable for a registration name of its own. I think we did finally find a few that we did register. I'll have to do some research to find out which ones, but even If I do find out, they have probably faded into anonimity and now are being called something else.
We are now in the process of trying to set up a really good registry and we have a volunteer from this DG forum Alias Tammi Frank who is going to be "The Registry Master". I will let you all know how we are going to proceed as soon as I can get all the loose ends tied up and consult with Tammi on how we should proceed.
Ann
Cool, Ann W. Thanks for the clarification. I will be THRILLED to have such a registery.
Ann S.
GREAT!! So glad to hear it!
